Crystal structure of 5-chloro­methyl-N-methyl-4-[(4-phenyl-1,2,3-triazol-1-yl)meth­yl]isoxazolidine-3-carboxamide

The title compound crystallized with two independent mol­ecules in the asymmetric unit. Each mol­ecule has three stereogenic centres with configurations 2(S), 3(S) and 4(R), confirmed by resonant scattering.

Abstract

The title compound, C₁₅H₁₈ClN₅O₂, crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. In both mol­ecules, the isoxazolidine rings have an envelope conformation with the O atoms at the flap positions. Each mol­ecule has three stereogenic centres with configurations 2(S), 3(S) and 4(R), confirmed by resonant scattering. Their conformations are significantly different, for example in mol­ecule A the phenyl ring is inclined to the triazole ring by 32.5 (2)°, while in mol­ecule B the corresponding dihedral angle is 10.7 (2)°. In the crystal, the A and B mol­ecules are linked via an N—H⋯O and a C—H⋯O hydrogen bond. These units are linked by C—H⋯O and C—H⋯N hydrogen bonds, forming slabs parallel to the ab plane. There are C—H⋯π inter­actions present within the slabs.

Chemical context  

The 1,3-dipolar cyclo­addition of nitro­nes to alkenes provides a straightforward route to isoxazolidines (Frederickson, 1997 ▸; Gothelf et al., 2002 ▸). Nitrone cyclo­adducts are attractive inter­mediates for the synthesis of several classes of natural products and biologically active compounds, such as unnatural amino­acids (Aouadi, et al., 2006 ▸) and alkaloids; for example (+)-febrifugine, (−)-indolizidine 209B (Smith et al., 1988 ▸), (+)-sedridine (Louis & Hootelé, 1995 ▸, 1997 ▸; Huisgen, 1984 ▸). We report herein on the synthesis, the mol­ecular structure and the spectroscopic data of the title compound, (2).

Structural commentary  

The title compound (2), Fig. 1 ▸, crystallized in the non-centrosymmetric space group P2₁, with two independent mol­ecules (A and B) in the asymmetric unit. Each mol­ecule has three stereogenic centres with configurations 2(S), 3(S) and 4(R), confirmed by resonant scattering [Flack parameter = −0.012 (6)]. In mol­ecule B there is an intra­molecular N—H⋯N contact present (Table 1 ▸).

The conformations of the two mol­ecules differ significantly, as seen in the overlay fit of the two mol­ecules (Fig. 2 ▸). In mol­ecule A the phenyl ring is inclined to the triazole ring by 32.5 (2)°, while in mol­ecule B the corresponding dihedral angle is 10.7 (2)°. The torsion angle C6—C7—C8—C13 is 31.5 (5)° in mol­ecule A, while torsion angle C21—C22—C23—C24, is −9.0 (5)° in mol­ecule B. The isoxazolidine rings (O1/N1/C2–C4 in mol­ecule A and O3/N6/C17–C19 in mol­ecule B) adopt envelope conformations. In mol­ecule A atom O1 is displaced by 0.566 (2) Å from the mean plane through atoms N1/C2–C4, while in mol­ecule B atom O3 is displaced by 0.528 (2) Å from the mean plane through atoms N6/C17–C19. Their mean planes are inclined to the relevant triazole ring by 53.95 (19)° in mol­ecule A and by 62.32 (18)° in mol­ecule B.

AutoMolFit (Spek, 2009 ▸) of the two independent mol­ecules (A black, B red) of compound (2).

The triazole N—N distances N2—N3 and N3—N4 in mol­ecule A are 1.340 (4) and 1.307 (4) Å, respectively, and in mol­ecule B distances N7—N8 and N8—N9 are 1.346 (3) and 1.305 (4) Å, respectively. They are close to the values reported for related triazole compounds, for example 2-allyl-3-[(1-benzyl-1H-1,2,3-triazol-4-yl)meth­oxy]-4-meth­oxy­phenol (Chang et al., 2014 ▸), with distances 1.357 (9) and 1.336 (7) Å. The N—O bond lengths of the isoxazolidine rings are O1—N1 = 1.442 (3) Å in A and O3—N6 = 1.445 (4) Å in B, also close to values reported for related compounds (Lee et al., 2010 ▸; Molander & Cavalcanti, 2013 ▸).

Supra­molecular features  

In the crystal of (2), the two independent mol­ecules are linked via an N—H⋯O and a C—H⋯O hydrogen bond (Table 1 ▸ and Fig. 3 ▸). These units are then linked via C—H⋯O and C—H⋯N hydrogen bonds, forming slabs lying parallel to the ab plane (Table 1 ▸ and Fig. 3 ▸). Within the slabs there are C—H⋯π inter­actions present involving symmetry-related A mol­ecules (Table 1 ▸).

Synthesis and crystallization  

The title compound, (2), was synthesized in two steps. Starting with a 1,3-dipolar cyclo­addition between (1S,2S,5S)-3′-(azido­meth­yl)-2′-(cholormeth­yl)-2-isopropyl-5,5′-di­methyl­dihydro-5′H-spiro­[cyclo­hexane-1,6′-imidazo[1,5-b]isoxasol]-4′(5′H)-one and phenyl­acetyl­ene lead to the formation of 1,2,3-triazolyl-functionalized isoxazolidine, compound (1) [yield 88%]. The cyclo­adduct (1) (200 mg, 0.42 mmol) was then dissolved in Ac₂O (2 ml), AcOH (3 ml), concentrated H₂SO₄ (0.8 ml) and the reaction was stirred at 323 K for 7 h. After cooling to 273 K, an aqueous solution of 5% NaOH was added drop wise over a period of 2 h until pH 8. The mixture was then poured slowly into a saturated aqueous NaHCO₃ solution (280 ml). The resulting mixture was extracted with CH₂Cl₂ (3 × 100 ml) and the combined organic phases were dried with Na₂SO₄. After filtration and evaporation of the solvents under reduced pressure, the residue was purified by flash chromatography (silica gel: EtOAc/PE, 8:2) to afford the desired title compound (2) as a white solid (97 mg, yield 69%); see Fig. 4 ▸. Colourless block-like crystals of (2) were obtained by slow evaporation of a solution in di­chloro­methane.

Spectroscopic investigations  

The spectroscopic measurements are consistent with the crystal structure of (2). High-resolution mass spectrometry in positive-ion mode gave an [M + H]⁺ ion of 336.1221 m/z, close to the calculated mass of 336.1222 m/z. The ¹H NMR spectrum of (2) shows the presence the triazole ring proton at 7.96 p.p.m. The ¹³C NMR spectrum confirms the existence of the three, C2, C3 and C4, stereogenic centres (80.3 p.p.m., 64.2 p.p.m. and 48.4 p.p.m., respectively).

Special details

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.
