The crystal structure and absolute configuration of two new nelfinavir analogs have been determined. Inter­molecular hydrogen bonding leads to two-dimensional sheets in one analog and one-dimensional chains in the other.

Abstract

The crystal structure and absolute configuration of the two new title nelfinavir analogs, C₂₄H₃₅ClN₄O₅, (I), and C₂₇H₃₉ClN₄O₅, (II), have been determined. Each of these mol­ecules exhibits a number of disordered moieties. There are intra­molecular N—H⋯O hydrogen bonds in both (I) and (II). In (I) it involves the two carboxamide groups, while in (II) it involves the N-tert-butyl carboxamide group and the 2-hydroxyl O atom. The inter­molecular hydrogen bonding in (I) (O—H⋯O and N—H⋯O) leads to two-dimensional sheets that extend parallel to the ac plane. The inter­molecular hydrogen bonding in (II) (O—H⋯O) leads to chains that extend parallel to the a axis.

Chemical context  

Nelfinavir (Viracept) is an FDA approved HIV protease inhibitor identified through structure-based design with a low nanomolar inhibitory concentration against the HIV aspartyl protease (Kaldor et al., 1997 ▸). Although nelfinavir is no longer recommended as a first-line treatment against HIV due to its inferior efficacy compared to alternative protease inhibitors (Panel on Anti­retroviral Guidelines, 2015 ▸), it has been found to have a number of additional biological activities that may have therapeutic utility, including anti­viral (against other human viruses) (Yamamoto et al., 2004 ▸; Kalu et al., 2014 ▸), anti­cancer (Gantt et al., 2013 ▸; Koltai, 2015 ▸), and anti­virulence activity (Maxson et al., 2015 ▸). However, nelfinavir was originally designed with only the HIV protease active site in mind and the structure is likely not optimal for binding to the alternative targets involved in these other activities. We recently reported on the synthesis of a collection of nelfinavir analogs that may be of inter­est for efforts to repurpose the drug (Maxson et al., 2015 ▸).

The syntheses of the title compounds were achieved by a previously reported route that utilizes the configuration of the amino acid starting material to control the stereochemical outcome of the sodium borohydride reduction of the chloro­methyl ketone (Kaldor et al., 1997 ▸). However, the reduction of compound (I), derived from achiral glycine, results in a racemic mixture (Fig. 1 ▸), while the reduction of compound (II), derived from l-proline, does not benefit from a strong directing influence from the existing chiral center (Fig. 2 ▸). The products of the two reductions were carried forward through the remainder of each synthesis to generate the title compounds. The absolute configurations of compounds (I) and (II), as well as the conformations they adopt due to the increased flexibility and rigidity, respectively, relative to nelfinavir was investigated by X-ray diffraction.

Structural commentary  

The core mol­ecular structures of (I) and (II) are comprised of N-tert-butyl-2-(2-hy­droxy­alk­yl)deca­hydro­iso­quinoline-3-carb­ox­amide groups. The difference between the two species comes from the substitution at the N position of the deca­hydro­iso­quinoline group. Compound (I) has a (2-chloro-4-nitro­benzamido)-2-hy­droxy­propyl group at the N-atom position of the deca­hydro­iso­quinoline ring (Fig. 3 ▸). Compound (II) has a (2-chloro-4-nitro­benzo­yl)pyrrolidin-2-yl)-2-hy­droxy­ethyl group at the N-atom position (Fig. 4 ▸).

There is disorder of the Cl group in (I) over two positions with the site occupancies refining to 0.941 (8) and 0.059 (8) for Cl1 and Cl1B, respectively. The nitro group is disordered over two positions, with the site occupancies refining to 0.60 (2) and 0.40 (2). The NO₂ group in one orientation is essentially coplanar with the phenyl ring [O1B—N1B—C4—C3; τ = 1(2)°] and in the other orientation is twisted slightly more out of plane [O1—N1—C4—C3; τ = −9.0 (13)°]. Both six-membered rings of the deca­hydro­iso­quinoline group in (I) adopt a chair conformation, the dihedral angle between the best-fit planes of the cyclo­hexyl and piperidine moieties is 119.9 (15)°. There is one intra­molecular hydrogen-bonding inter­action in (I) which involves the two carboxamide groups (N2—H2⋯O5; Table 1 ▸). The Flack x parameter of −0.008 (18) and the Hooft y parameter of −0.010 (19) indicate that the absolute configuration of (I) has been assigned correctly.

There are multiple disordered moieties in (II), the nitro group is disordered over two positions with the site occupancies for the two orientations refining to 0.967 (6) and 0.033 (8). In both orientations, the NO₂ group is twisted out of the plane of the phenyl ring; the major orientation is twisted out of the plane less [O1—N1—C3—C2; τ = 10.9 (4)°] than the minor orientation [O1B—N1B—C3—C2; τ = −26 (6)°]. The carbonyl C7—O3 group is disordered over two positions, with the site occupancies refining to 0.58 (2) and 0.42 (2). In the minor orientation, the CO group is nearly normal to the plane of the phenyl ring [O3B—C7B—C6—C5; τ = −89 (3)°], while the major orientation is significantly less out of plane [O3—C7—C6—C5; τ = −44 (3)°]. The final two disordered moieties of (II) are a portion of the pyrrolidin-2-yl group and the three methyl groups of tert-butyl. The C10 and C11 atoms of the pyrrolidin-2-yl group are disordered over two positions, with site occupancies of 0.669 (16) and 0.331 (16). The tert-butyl methyl groups are also disordered over two positions via a slight rotation around the N4—C24 bond, the site occupancies refining to 0.811 (17) and 0.189 (17). Similar to (I), both six-membered rings of the deca­hydro­iso­quinoline group in (II) adopt a chair conformation, with a dihedral angle between the best-fit planes of the cyclo­hexyl and piperidine moieties of 116.3 (17)°. There is one weak intra­molecular hydrogen-bonding inter­action in (II), involving the N-tert-butyl carboxamide group and the 2-hydroxyl O atom (N4—H4C⋯O4; Table 2 ▸). The Flack x parameter of 0.036 (19) and the Hooft y parameter of 0.03 (2) indicate that the absolute configuration of (II) has been assigned correctly.

Supra­molecular features  

The extended structure of (I) is a two-dimensional sheet of hydrogen-bonded mol­ecules extending in the ac plane (Fig. 5 ▸ a). Each mol­ecule of (I) is hydrogen bonded to four neighboring mol­ecules via O—H⋯O and N—H⋯O inter­actions; the details of these inter­actions can be found in Table 1 ▸. The two-dimensional layers stack in an ABAB pattern along the crystallographic b axis (Fig. 5 ▸ b). The layers are separated by the bulky deca­hydro­iso­quinoline groups, which protrude above and below the sheets. The layers alternate between these bulky groups pointing ‘left’ and ‘right’, this along with a slight offset between the A and B layers allows them to inter­digitate.

Only the major component of disordered sites are shown. Red dashed lines indicate inter­molecular hydrogen bonding and blue dashed lines indicate intra­molecular hydrogen bonding.

The extended structure of (II) is a one-dimensional chain of hydrogen-bonded mol­ecules extending parallel to the crystallographic a axis (Fig. 6 ▸ a). Each mol­ecule of (II) is hydrogen bonded to two neighboring mol­ecules via O—H⋯O inter­actions, the details of these inter­actions can be found in Table 2 ▸. The one-dimensional chains are separated by the bulky deca­hydro­iso­quinoline groups and the tert-butyl groups, which prevent the chains from linking via further hydrogen-bonding inter­actions (Fig. 6 ▸ b).

Database survey  

A search of the Cambridge Crystallographic Database (CSD; Groom & Allen, 2014 ▸) returns only three crystal structures with the N-(tert-but­yl)deca­hydro­iso­quinoline-3-carboxamide core. One of the structures is N-(tert-but­yl)deca­hydro­iso­quinoline-3-carboxamide (CSD refcode COVYAO; Zhao et al., 2006 ▸). The other two mol­ecules are nelfinavir derivatives like (I) and (II), which were isolated during optimization of the synthesis. The difference between these two mol­ecules comes via the substitution at the N-atom position of the deca­hydro­iso­quinoline group.

One compound has a 3-amino-2-hy­droxy-4-(phenyl­sulfan­yl)butyl group in this position (CSD refcode QONJUY; Inaba et al., 2000 ▸) and the other has a 3-acet­oxy-2-(3-acet­oxy-2-methyl­benzoyl­amino)-4-(phenyl­sulfan­yl)butyl group at the N-atom position (CSD refcode GONKOJ; Inaba et al., 1998 ▸). Each of these mol­ecules has intra­molecular N—H⋯O hydrogen bonding. In QONJUY it involves the two carboxyamide groups similar to the situation in compound (I). In GONKOJ it involves the N-tert-butyl carboxamide group and the 2-hydroxyl O atom similar to the situation in compound (II). The core structure of each of these previously reported materials is similar to (I) and (II) in that both six-membered rings of the deca­hydro­iso­quinoline groups adopt chair conformations. The dihedral angle between the best-fit planes of the cyclo­hexyl and piperidine moieties for the 3-amino-2-hy­droxy-4-(phenyl­sulfan­yl)butyl-substituted mol­ecule is 117.1 (18)°. Similarly, this angle for the 3-acet­oxy-2-(3-acet­oxy-2-methyl­benzoyl­amino)-4-(phenyl­sulfan­yl)butyl-substituted mol­ecule is 116.8 (14)°.

Synthesis and crystallization  

Compound (I) was synthesized through the inter­mediate chloro­methyl hy­droxy 4 (Fig. 1 ▸). Chloro­methyl ketone 3 (571 mg, 2.36 mmol) was dissolved in di­chloro­methane (7 ml) and methanol (4 ml) under nitro­gen. The reaction was cooled to 273 K and sodium borohydride (63 mg, 1.65 mmol) was added in one portion. The reaction was stirred cold for 1h before being quenched by the slow addition of 2 M HCl (2 ml). The reaction was dried and the solid was dissolved in ethyl acetate. The product was washed twice with water and once with brine, dried over sodium sulfate, and concentrated by rotary evaporation. The product was purified by silica flash column chromatography (gradient of 0–8% EtOAc in DCM) to yield racemic 4 as a colorless oil (yield 423 mg, 75% yield). ¹H NMR (500 MHz, CDCl₃): δ 7.33–7.28 (complex, 5H), 5.63 (t, J = 6 Hz, 1H), 5.06 (s, 2H), 3.88 (s, 2H), 3.48 (m, 2H), 3.39 (m, 1H), 3.22 (m, 1H). ¹³C NMR (500 MHz, CDCl₃): δ 157.23, 135.93, 128.36, 128.06, 127.91, 70.52, 66.90, 46.44, 43.96. HRMS (m/z): [M + H]⁺ calculated for C₁₁H₁₅ClNO₃, 244.0740; observed, 244.0741. For the synthesis of compound (I), compound 5 (104 mg, 0.233 mmol) was dissolved in methanol (15 ml) with 10% palladium on carbon (74 mg, 0.070 mmol). The solution was degassed for 30 min before being placed under 1 atm of hydrogen and stirred for 2 h at room temperature. The reaction was filtered through celite, dried to a solid, and taken up in tetra­hydro­furan (5 ml). 2-Chloro-4-nitro­benzoic acid (52 mg, 0.256 mmol), 3-[3-(di­methyl­amino)­prop­yl]-1-ethyl­carbodi­imide hydro­chloride (49 mg, 0.256 mmol), and hy­droxy­benzotriazole hydrate (42 mg, 0.256 mmol) were added and the reaction was stirred at room temperature overnight. The reaction was taken up in ethyl acetate, washed once with sodium bicarbonate and once with brine, and dried over sodium sulfate. The product was purified by silica flash-column chromatography (gradient of 0–3% MeOH in DCM) to yield (I) as a yellow solid (yield 77 mg, 67%). Crystals suitable for X-ray diffraction were obtained from the vapor diffusion of pentane into a solution of compound (I) in ethyl acetate at room temperature. ¹H NMR (500 MHz, CDCl₃): δ 8.41 (q, J = 4 Hz, 1H), 8.24 (d, J = 2 Hz, 1H), 8.13 (dd, J1 = 2 Hz, J2 = 8.5 Hz, 1H), 7.76 (d, J = 8.5 Hz, 1H), 5.60 (s, 1H), 4.04 (m, 2H), 3.47 (dt, J1 = 4 Hz, J2 = 14 Hz, 1H), 3.35 (br, 1H), 2.71 (dd, J1 = 2 Hz, J2 = 11.5 Hz, 1H), 2.49 (dd, J1 = 3 Hz, J2 = 11.5 Hz, 1H), 2.36 (dd, J1 = 10 Hz, J2 = 12.5 Hz, 1H), 2.22 (dd, J1 = 5 Hz, J2 = 12.5 Hz, 1H), 2.18 (dd, J1 = 3 Hz, J2 = 11.5 Hz, 1H), 1.95 (q, J = 12 Hz, 1H), 1.80–1.08 (complex, 20H). ¹³C NMR (500 MHz, CDCl₃): δ 174.16, 167.06, 148.39, 142.00, 132.80, 130.18, 124.96, 121.56, 70.40, 68.29, 59.09, 57.54, 51.27, 43.27, 35.83, 33.55, 31.02, 30.86, 28.39, 26.19, 25.52, 20.18. HRMS (m/z): [M + H]⁺ calculated for C₂₄H₃₆ClN₄O₅, 495.2374; observed, 495.2376.

Compound (II) was synthesized through the inter­mediate chloro­methyl hydroxyl 7 (Fig. 2 ▸). Chloro­methyl ketone 6 (860 mg, 3.05 mmol) was dissolved in di­chloro­methane (7 ml) and methanol (4 ml) under nitro­gen. The reaction was cooled to 273 K and sodium borohydride (81 mg, 2.14 mmol) was added in one portion. The reaction was stirred cold for 1h before being quenched by the slow addition of 2 M HCl (2 ml). The reaction was dried and the solid was dissolved in ethyl acetate. The product was washed twice with water and once with brine, dried over sodium sulfate, and concentrated by rotary evaporation. Thin-layer chromatography (TLC) analysis showed two diastereomers with the higher R _F compound being the (S,R) product. Both diastereomers were purified by silica flash-column chromatography (gradient of 0–10% EtOAc in DCM) to yield the (S,S)-isomer as a white solid (yield 279 mg, 32%) and (S,R)-isomer (7) as a white solid (yield 429 mg, 50%). Characterization of the (S,R)-isomer (7): ¹H NMR (500 MHz, CDCl₃): δ 7.37–7.28 (complex, 5H), 5.13 (dd, J1 = 12.5 Hz, J2 = 16 Hz, 2H), 4.95 (d, J = 2 Hz, 1H), 4.11 (m, 1H), 3.81 (br s, 1H), 3.72 (d, J = 11 Hz, 1H), 3.55 (m, 2H), 3.37 (m, 1H), 2.03 (m, 1H), 1.89 (m, 1H), 1.81 (m, 1H), 1.72 (m, 1H). ¹³C NMR (500 MHz, CDCl₃): δ 157.52, 136.04, 128.27, 127.87, 127.65, 74.69, 67.22, 60.57, 47.91, 47.05, 28.12, 23.94. HRMS (m/z): [M + H]⁺ calculated for C₁₄H₁₉ClNO₃, 284.1053; observed, 284.1055. For the synthesis of compound (II), compound 8 (218 mg, 0.620 mmol) was dissolved in tetra­hydro­furan (6 ml) with 2-chloro-4-nitro­benzoic acid (138 mg, 0.682 mmol), 3-[3-(di­methyl­amino)­prop­yl]-1-ethyl­carbodi­imide hydro­chloride (131 mg, 0.682 mmol), and hy­droxy­benzotriazole hydrate (111 mg, 0.682 mmol). The reaction was stirred at room temperature overnight. The reaction was taken up in ethyl acetate, washed once with sodium bicarbonate and once with brine, and dried over sodium sulfate. The product was purified by silica flash-column chromatography (gradient of 0–5% MeOH in DCM) to yield (II) as a yellow solid (yield 248 mg, 72%). Crystals suitable for X-ray diffraction were obtained by layering pentane over a solution of compound (II) in di­chloro­methane at room temperature. ¹H NMR (500 MHz, CDCl₃): δ 8.31 (d, J = 2 Hz, 1H), 8.20 (dd, J1 = 2 Hz, J2 = 8.5 Hz, 1H), 7.54 (d, J = 8.5 Hz, 1H), 6.87 (s, 1H), 5.31 (s, 1H), 4.36 (m, 1H), 3.99 (m, 1H), 3.24 (m, 2H), 2.91 (d, J = 11 Hz, 1H), 2.63 (m, 2H), 2.18–1.13 (complex, 26H). ¹³C NMR (500 MHz, CDCl₃): δ 173.83, 172.95, 148.31, 142.45, 128.53, 124.96, 122.35, 121.69, 69.81, 69.73, 60.88, 58.37, 57.98, 50.55, 50.51, 49.05, 35.84, 33.23, 31.07, 30.80, 28.56, 28.20, 26.20, 25.46, 24.53, 20.16. HRMS (m/z): [M + H]⁺ calculated for C₂₇H₄₀N₄O₅Cl, 535.2687; observed, 535.2692.

Refinement  

Crystal data, data collection and structure refinement details for (I) and (II) are summarized in Table 3 ▸. Structural models consisting of the target mol­ecules were developed for (I) and (II). Several disordered sites on each mol­ecule were modeled with disorder. In each case, like distances were restrained to be similar. Since the major and minor components of each disordered site are in such close proximity to each other, the displacement parameters were constrained to be equal. Methyl H atom positions, R—CH₃, were optimized by rotation about R—C bonds with idealized C—H, R–H and H⋯H distances. All hy­droxy and amine H atoms were located in a difference Fourier map in good hydrogen-bonding environments (Hamilton & Ibers, 1968 ▸) and their distances were allowed to refine. The O4—H4B distance in (II) was restrained to be 0.84 (2) Å. The remaining H atoms were included as riding idealized contributors. Methyl, hy­droxy and amine H atomU values were assigned as 1.5 times U _eq of the carrier atom; remaining H atom U values were assigned as 1.2 times the carrier atom U _eq. On the basis of 2237 unmerged Friedel opposites, the fractional contribution of the inverted twin component was negligible (Flack, 1983 ▸; Flack & Bernardinelli, 2000 ▸) for (I). The absolute structure parameter y was calculated using PLATON (Spek, 2009 ▸). The resulting value was y = −0.010 (19), indicating that the absolute structure has been determined correctly (Hooft et al. 2008 ▸). On the basis of 2720 unmerged Friedel opposites, the fractional contribution of the inverted twin component was negligible (Flack, 1983 ▸; Flack & Bernardinelli, 2000 ▸) for (II). The absolute structure parameter y was calculated using PLATON (Spek, 2009 ▸). The resulting value was y = 0.03 (2) indicating that the absolute structure has been determined correctly (Hooft et al. 2008 ▸).

Experimental. One distinct cell was identified using APEX2 (Bruker, 2014). Four frame series were integrated and filtered for statistical outliers using SAINT (Bruker, 2014) then corrected for absorption by integration using SHELXTL/XPREP V2005/2 (Bruker, 2014) before using SAINT/SADABS (Bruker, 2014) to sort, merge, and scale the combined data No decay correction was applied.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Structure was phased by direct (Sheldrick, 2015). Systematic conditions suggested the ambiguous space group. The space group choice was confirmed by successful convergence of the full-matrix least-squares refinement on F2. The final map had no significant features. A final analysis of variance between observed and calculated structure factors showed no dependence on amplitude or resolution.

Experimental. One distinct cell was identified using APEX2 (Bruker, 2014). Four frame series were integrated and filtered for statistical outliers using SAINT (Bruker, 2014) then corrected for absorption by integration using SHELXTL/XPREP V2005/2 (Bruker, 2014) before using SAINT/SADABS (Bruker, 2014) to sort, merge, and scale the combined data. No decay correction was applied.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Structure was phased by direct (Sheldrick, 2015) methods. Systematic conditions suggested the ambiguous space group. The space group choice was confirmed by successful convergence of the full-matrix least-squares refinement on F2. The final map had no significant features. A final analysis of variance between observed and calculated structure factors showed little dependence on amplitude and resolution.
