Enanti­opure (S)-butan-2-yl N-(4-x-phen­yl)thio­carbamates, x = NO₂, OCH₃, F, and Cl

Enanti­opure (S)-butan-2-yl-N-(4-x-phen­yl)thio­carbamates, x = NO₂, OCH₃, F, and Cl were synthesized from reacting aryl iso­thio­cyanate with (S)-2-butanol to form new chiral crystals as the basis for future research into their non-linear physical and potentially biological properties.

Abstract

The structures of (S)-butan-2-yl N-(4-nitro­phen­yl)thio­carbamate, C₁₁H₁₄N₂O₃S, (I), (S)-butan-2-yl N-(4-meth­oxy­phen­yl)thio­carbamate, C₁₂H₁₇NO₂S, (II), (S)-butan-2-yl N-(4-fluoro­phen­yl)thio­carbamate, C₁₁H₁₄FNOS, (III), and (S)-butan-2-yl N-(4-chloro­phen­yl)thio­carbamate, C₁₁H₁₄ClNOS, (IV), all at 100 K, have monoclinic (P2₁) symmetry with two independent mol­ecules in the asymmetric unit. The Flack absolute structure parameters in all cases confirm the absence of inversion symmetry. The structures display N—H⋯S hydrogen bonds, resulting in R ₂ ²(8) hydrogen-bonded ring synthons connecting the two independent mol­ecules. Despite the ring synthon, the packing follows two distinct patterns, with (I) and (IV) ‘pancaking’ along the b-axis direction, while the other two ‘sandwich’ in layers perpendicular to the b axis. Crystal morphologies were determined theoretically via the BFDH (Bravais, Friedel, Donnay–Harker) model and agree qualitatively with the experimentally indexed results. One of the butyl substituent of (II) exhibits structural disorder.

1. Chemical context

This research is part of an undergraduate study into creating new chiral model compounds from reacting a chiral moiety with another mol­ecule to combine specific features of both. Initially, iso­thio­cyanates were reacted with α-methyl­benzyl­amine to form chiral thio­urea derivatives (Kaminsky et al., 2010 ▸), whereas here, the poisonous iso­thio­cyanates were reacted with (S)-2-butanol to form thio­carbamates with possible protein-docking capability (Bull & Breese, 1978 ▸; Du et al. 2020 ▸). Specifically, (S)-butan-2-yl-N-(4-x-phen­yl)thio­carb­amates were synthesized from enanti­opure (S)-2-butanol and 4-x-phenyl­iso­thio­cyanate, x = NO₂, OCH₃, F, and Cl. Similar thio­carbamates have been investigated previously for their biological activities (Ghosh & Brindisi, 2015 ▸).

2. Structural commentary

Iso­thio­cyanates were selected because of the ease with which the –N=C=S functional group can be reacted with amines or alcohols to form thio­ureas or thio­carbamates, which in turn are well suited for simple crystal-growth studies. The –R=S linkage builds out selected hydrogen bonds, structuring the packing of the mol­ecule and thereby enhancing crystal growth. In addition, the sulfur atom has sufficient anomalous scattering capability with Mo radiation, which permits absolute structure determinations via single crystal X-ray diffraction. Further, from comparing a series of crystals with small chemical variations, we hoped to gain insight into the functionality of those inter­changed moieties, here NO₂, OCH₃, F, and Cl in the 4-x location on the structures of the phenyl­thio­carbamates. All four structures crystallize in the chiral space group P2₁ of the monoclinic system. Bond lengths and angles are in the expected ranges. We observed two pairings, where the 4-NO₂ and 4-Cl crystals exhibited a similarly short b-axis, whereas OCH₃ and F in the 4-x location had the longest axis dimensions along b. The chirality of the compounds was confirmed by the absolute structure parameters [(I)–(IV): −0.02 (3), −0.04 (4), 0.17 (13), and 0.022 (14), respectively].

3. Supra­molecular features

In each structure shown in Fig. 1 ▸, pairs of the title mol­ecules organize via the thio­amide {⋯H—N—C=S}₂ into – (8) hydrogen-bonded ring synthons (Allen et al., 1999 ▸). All six non-H atoms of the ring synthons are coplanar with r.m.s. deviations from the plane of 0.026 to 0.044 Å between the four synthons. The N⋯S distances of the synthon bonds range from 3.314 (3) to 3.410 (2) Å (Tables 1 ▸–4 ▸ ▸ ▸). Hydrogen-to-acceptor distances are similar as well, however, the D—H⋯A angles appear to deviate slightly more from a ‘straight’ geometry in compounds (I) and (IV) than in (II) and (III). With the exception of (III), the sulfur atoms act as acceptors for two hydrogen bonds with a major N—H⋯S and a weaker secondary C—H⋯S inter­action, which causes the synthon geometry to shift slightly towards the secondary inter­actions. In (I), we observe a weak inter­action with the ortho-C—H of the phenyl groups (C2—H2⋯S2, C13—H13⋯S1). The inter­action is strong enough to also cause the phenyl rings to become coplanar with the synthon plane. In (II), the secondary inter­action is with a proton of the meth­oxy group from a symmetry-related mol­ecule. For (III), consolidating S⋯F non-covalent inter­molecular inter­actions (Thorley & McCulloch, 2018 ▸) are found at 3.62 (1) Å instead of an H⋯S inter­action. The phenyl rings in (IV) are tilted towards the ring synthon plane, causing the ortho-C—H distance to the sulfur atoms to be of lesser importance than in (I). Thus, for each case shown, we see a distinctly different bond environment of the sulfur atoms.

The packing follows two distinct patterns, with (I) and (IV) ‘pancaking’ along the b-axis direction, while the other two ‘sandwich’ in layers perpendicular to the b-axis, see Fig. 2 ▸.

Figure 2.

Packing of the structures of this report. (I), (IV): view slightly inclined to the b axis·(II), (III): view approximately along the a axis. Disorder omitted for clarity.

Packing of (II), (III): The 4-x-phenyl moiety is approximately parallel to the ac plane. The (8) hydrogen-bonded rings orient roughly parallel to the c plane in (II) or the bc plane in (III). The phenyl­carbamate double layers are separated by layers containing the (S)-butan-2-yl moieties. Short distances between the phenyl plane and a symmetry-related OCH₃ group are seen in (II). As a result of the S—F inter­action in (III), the F atoms are not found as close to a phenyl group, but both are in hydrogen-bonding distance to a methyl group of a symmetry-related butyl moiety.

Packing of (I), (IV): The (8) hydrogen-bonded rings are roughly parallel to the bc planes. Each dimer stacks entirely like ‘pancakes’ along the short b-axis, with a separate stack for the 2₁ axis-related dimers. The dimers are inclined to b so that the NO₂ group of (I), or Cl of (IV) are found at a short distance to the phenyl of the mol­ecule of the next layer. The NO₂–phenyl plane distances are not the same for the independent phenyl moieties and are measured at 2.99 (2) and 3.169 (16) Å in (I). In (IV), the Cl–phenyl plane distances are 3.062 (3) and 3.316 (12) Å. These distances are short and may indicate inter­action between the phenyl ring and the 4-x-groups, (NO₂, Cl). One oxygen atom of the NO₂ in (I) establishes a hydrogen bond with a proton of a symmetry-related phenyl ring.

The different stacking models seem not to correlate with the electronegativity of the ligands, which is generally known to be in decreasing order NO₂ > F > OCH₃ > Cl (Pauling, 1932 ▸).

Morphologies of the four compounds, drawn with WinXMorph (Kaminsky, 2005 ▸) are shown in Fig. 3 ▸. For (I), the indexed faces are in decreasing order (increasing central distance): pinacoids 〈1 0 1〉, 〈1 0 〉, sphenoides 〈2 1 2〉, 〈 〉. For (IV), the face indexing yielded pinacoids 〈1 0 1〉, 〈1 0 〉, sphenoides 〈5 2〉, 〈 1 〉. This observation was confirmed qualitatively by BFDH (Bravais, Friedel, Donnay–Harker) model simulations (Bravais, 1866 ▸; Friedel, 1907 ▸; Donnay & Harker, 1937 ▸) using WinXMorph (Kaminsky, 2007 ▸) where the dominant crystal facets are pinacoids 〈001〉, 〈100〉, 〈10 〉, and sphenoides 〈1 1 0〉, 〈0 1 1〉, 〈1 0〉, 〈0 1〉, 〈1 1 〉, and 〈1 1〉 in decreasing order. For (I) and (IV), it is notable that the 〈0 0 1〉, 〈1 0 0〉 and calculated sphenoids were not observed. For compounds (II) and (III), a more prismatic morphology was observed. The BFDH model yields in both cases, in decreasing face-size order: pinacoids 〈0 1 0〉, 〈1 0 0〉, 〈1 0 〉, sphenoids 〈1 1 0〉, 〈1 0〉, 〈1 1 〉, 〈1 〉. The observed faces in (II) are 〈0 1 〉, 〈0 1 0〉, 〈0 0〉, 〈1 0 0〉, 〈2 1 2〉. Compound (III) grew with 〈0 〉, 〈0 1 〉, and 〈1 0 0〉 faces.

The morphologies of the samples used to obtain structures for this report and the result of BFDH calculations based on the structures.

The BFDH model is entirely based on the metrical and space-group symmetry. It does not account for solvent–surface effects. Thus, differences of growth rates due to such effects in the real samples may often distort the habitus, as well as changing the occurrence of faces.

4. Database survey

The structures of this report are not found in the Cambridge Structural Database (CSD version 5.42; Groom et al., 2016 ▸). Earlier, we deposited related structures to the CSD, viz. the racemic (RS)-butan-2-yl equivalent structures to (I), (II), and (IV), denoted with a prime: (I′): CCDC 2249338, (II’): 2249339, (IV’): 2249336 (Kaganyuk et al., 2023 ▸). Instead of (III′), for which we got only a very low in quality obtained structure, we uploaded the 4-bromo structure (V′), CCDC 2249337. The 4-Cl (IV’) and 4-Br (V′) compounds, both in space group P2₁/c, exhibit very similar packing to that of (IV), despite the addition of the glide-plane symmetry. The other two crystallize in the triclinic space group P , and only the (RS)-butan-2-yl-4-CH₃ phenyl­thio­carbamate crystal builds out the (8) synthon, thus although likely, the thio­carbamates do not always exhibit this feature. A more general search for ‘thio­carbamate’ gave 315 hits, indicating that this substance group has been crystallized moderately often. Via a GOOGLE search (March 2023), ‘phenyl­thio­carbamate’ is found 9,370 times. Most of the compounds incorporate a center of symmetry, which is often compatible with an (8) synthon. In fact, the inter­net delivers over 43,000 results when searching for ‘N—H⋯S R22(8) synthon’ (GOOGLE search, March 2023). The number drops considerably, to 93, in a search for ’ring synthon in phenyl­thio­carbamates’. ‘Ring synthon in chiral phenyl­thio­carbamates’ yields only one reasonable result, already included here (Kaminsky et al., 2010 ▸).

5. Synthesis and crystallization

All chemicals were obtained from Sigma Aldrich. Compounds (I), (III), and (IV): 4 ml vials were charged with a stir bar, the aryl iso­thio­cyanate [0.100 g, 0.555 mmol (I), 0.653 mmol (III), 0.590 mmol (IV)] and 2(S)-butanol (82.3 mg, 1.1 mmol). Using a hot oil bath, the reaction was run at 381 K for 24 h. Compound (II): A 4 mL vial was charged with a stir bar and 2(S)-butanol (0.054 g, 0.726 mmol). While stirring, tri­ethyl­amine (0.011 g, 0.109 mmol) was added. After 5 minutes, the aryl iso­thio­cyanate (0.100 g, 0.605 mmol) was added dropwise. The reaction was allowed to continue for 24 h at 358 K. Subsequently, for all four compounds, the vials, after allowing to cool, were covered with filter paper and left in a vacuum oven at 343 K. The crude product was purified by flash column chromatography, and eluted with 1:4 ethyl acetate/hexane. Fractions were collected in 13 × 100 mm test tubes and were spotted for thin layer chromatography to locate the product. The fractions containing the product were rotovaped in a 25 ml round-bottom flask. The solid found in low yields was redissolved in a 1:4 methanol/ethanol solution and crystals grew via slow evaporation. (I): ¹H NMR (300 MHz, CDCl₃): δ 9.2638 (bs, 1H), 8.1926 (d, J = 7.1 Hz, 2H), 7.5520 (bs, 2H), 5.5528 (m, 1H), 1.7044 (m, 2H), 1.4038 (d, J = 6.3 Hz, 3H), 0.9634 (t, J = 7.4 Hz, 3H). (II): ¹H NMR (300 MHz,(CD₃)₂CO): δ 9.7438 (s, 1H), 7.5813 (m, 2H), 6.9070 (d, J = 9.1 Hz, 2H), 5.4819 (bs, 3H), 3.7847 (s, 3H), 1.7022 (m, 2H), 1.2948 (s, 3H), 0.9184 (t, J = 7.4, 3H). (III): ¹H NMR (300 MHz, CDCl3): δ 8.8978 (bs, 1H), 7.2240 (bs, 2H), 7.0147 (t, J = 8.5 Hz, 2H), 5.0768 (m, 1H), 1.7280 (m, 2H), 1.3461 (d, J = 6.5 Hz, 3H), 0.9316 (t, J = 7.5 Hz, 3H). (IV): ¹H NMR (300 MHz, CDCl₃): δ 8.7150 (bs, 1H), 7.2918 (d, J = 8.6 Hz, 2H), 7.2130 (bs, 2H), 5.5199 (m, 1H), 1.7269 (m, 2H), 1.3640 (d, J = 6.2 Hz, 3H), 0.9472 (t, J = 7.4 Hz, 3H).

6. Refinement

Crystal data, data collection, and structure refinement details are summarized in Table 5 ▸. Hydrogen atoms on carbon atoms were positioned geometrically, using a riding model, with C—H = 0.95–1.00Å. U _iso(H) = 1.2 (1.5 for methyl groups) times U _eq(C). The nitro­gen protons were refined positionally, with U _iso(H) = 1.2U _eq(N). The two phenyl groups of the independent mol­ecules of (III) were optimized to enhance the C—C bond precision with the C—C distance at 1.39 Å (AFIX 66). In (II), one of the two (S)-butan-2-yl moieties appeared threefold disordered, requiring restraint of the displacement parameters with a SIMU 0.01 command. One atom (C8) was constrained to the same displacement parameter for each fraction with EADP. The disordered geometries were linked through a SAME command to the geometry of the ordered moiety of the other mol­ecule, and distances of O1 to C8, C8B and C8C were restrained to be similar (SADI), all with default esds. The occupancies of the three fractions were 0.444 (4), 0.354 (4), and 0.202 (4).

(S)-2-Butyl N-(4-nitrophenyl)thiocarbamate (I) . Special details

Experimental. Crystals were mounted on a CryoloopTM (0.2–0.3mm, Hampton Research) with Paratone (R) oil. Between 7 to 12 data sets were collected to cover full Ewald spheres to a resolution of better than 0.75 Å. Crystals were held at 100 K with a Cryostream cooler, mounted to a Bruker APEXII single crystal X-ray diffractometer, Mo radiation (Bruker 2012), equipped with a fine-focus X-ray tube, Miracol X-ray optical collimator, and CCD detector. Crystal-to-detector distance was 40 mm and the exposure times were between 20 to 120 seconds per frame for all sets, pending on sample size. The scan widths were 0.5°. Crystal data, data collection, and structure refinement details are summarized in Table 5. The data were integrated and scaled using SAINT, SADABS within the APEX2 software package by Bruker (2012). Data work-up was done with SAINT (Bruker, 2012). Structures were solved with SHELXS (Sheldrick, 2008), and refined with SHELXL (Sheldrick 2015).

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

(S)-2-Butyl N-(4-methoxyphenyl)thiocarbamate (II) . Special details

Experimental. Crystals were mounted on a CryoloopTM (0.2–0.3mm, Hampton Research) with Paratone (R) oil. Between 7 to 12 data sets were collected to cover full Ewald spheres to a resolution of better than 0.75 Å. Crystals were held at 100 K with a Cryostream cooler, mounted to a Bruker APEXII single crystal X-ray diffractometer, Mo radiation (Bruker 2012), equipped with a fine-focus X-ray tube, Miracol X-ray optical collimator, and CCD detector. Crystal-to-detector distance was 40 mm and the exposure times were between 20 to 120 seconds per frame for all sets, pending on sample size. The scan widths were 0.5°. Crystal data, data collection, and structure refinement details are summarized in Table 5. The data were integrated and scaled using SAINT, SADABS within the APEX2 software package by Bruker (2012). Data work-up was done with SAINT (Bruker, 2012). Structures were solved with SHELXS (Sheldrick, 2008), and refined with SHELXL (Sheldrick 2015).

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

(S)-2-Butyl N-(4-fluorophenyl)thiocarbamate (III) . Special details

Experimental. Crystals were mounted on a CryoloopTM (0.2–0.3mm, Hampton Research) with Paratone (R) oil. Between 7 to 12 data sets were collected to cover full Ewald spheres to a resolution of better than 0.75 Å. Crystals were held at 100 K with a Cryostream cooler, mounted to a Bruker APEXII single crystal X-ray diffractometer, Mo radiation (Bruker 2012), equipped with a fine-focus X-ray tube, Miracol X-ray optical collimator, and CCD detector. Crystal-to-detector distance was 40 mm and the exposure times were between 20 to 120 seconds per frame for all sets, pending on sample size. The scan widths were 0.5°. Crystal data, data collection, and structure refinement details are summarized in Table 5. The data were integrated and scaled using SAINT, SADABS within the APEX2 software package by Bruker (2012). Data work-up was done with SAINT (Bruker, 2012). Structures were solved with SHELXS (Sheldrick, 2008), and refined with SHELXL (Sheldrick 2015).

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

(S)-2-Butyl N-(4-chlorophenyl)thiocarbamate (IV) . Special details

Experimental. Crystals were mounted on a CryoloopTM (0.2–0.3mm, Hampton Research) with Paratone (R) oil. Between 7 to 12 data sets were collected to cover full Ewald spheres to a resolution of better than 0.75 Å. Crystals were held at 100 K with a Cryostream cooler, mounted to a Bruker APEXII single crystal X-ray diffractometer, Mo radiation (Bruker 2012), equipped with a fine-focus X-ray tube, Miracol X-ray optical collimator, and CCD detector. Crystal-to-detector distance was 40 mm and the exposure times were between 20 to 120 seconds per frame for all sets, pending on sample size. The scan widths were 0.5°. Crystal data, data collection, and structure refinement details are summarized in Table 5. The data were integrated and scaled using SAINT, SADABS within the APEX2 software package by Bruker (2012). Data work-up was done with SAINT (Bruker, 2012). Structures were solved with SHELXS (Sheldrick, 2008), and refined with SHELXL (Sheldrick 2015).

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