(Received 27 February 2008; accepted 2 May 2008; online 17 May 2008)

The crystal structure of the title compound, C12H14N2O3S, exhibits intra­molecular C—H⋯S and inter­molecular C—H⋯S, C—H⋯O hydrogen bonds, C—S⋯N [S⋯N = 2.980 (2) Å, C—S⋯N = 145.78 (17)°] and C—H⋯π inter­actions; these inter­actions generate two C(5) chains and S(4), S(6) and R44(28) ring motifs. The isoxazole ring has an envelope conformation; the N atom, which is the flap atom, is displaced by 0.261 (2) Å from the plane defined by the remaining four atoms. The dihedral angle between the succinimide and thio­phene rings is 46.8 (2)°.

Comment top

A general principle for the synthesis of five-membered rings was introduced in 1960 as 1,3-dipolar cycloaddition and turned out to be remarkably widespread (Huisgen, 1960). Because of easy 1,3-dipolar cycloaddition reactions to alkenes, alkynes, isocyanates, isothiocyanates, phospharanes, sulphenes and sulphynl compounds, nitrones are the important intermediates in synthetic organic chemistry (Black et al., 1975). Especially, the nitrone-olefin 1,3-dipolar cycloaddition reaction is interesting since it can create three new contiguous stereogenic centers in a single step (Alibes et al., 2003). Both inter and intramolecular nitrone cycloaddition reactions have received attention because they are useful methods for the formation of heterocycles of biological active compounds (Kumar et al., 2003).

There has been an ever-increasing quest for modified nucleosides due to their potential applications in antiviral and anticancer therapies (Richman, 2001; De Clercq, 2002a,b,c). In a recent approach to modified nucleosides, the furanose ring has been replaced by other heterocyclic analogs (Chiacchio et al., 2003a). Among these N and O containing five-membered heterocycles, isoxazolidines, and isoxazoline derivatives have emerged as important candidates, and have been shown to display useful anticancer and antiviral properties (Chiacchio et al., 2003b). Consequently, synthetic studies on isoxazolidines have drawn considerable attention and 1,3-dipolar cycloadditions of nitrones afford the most straightforward route to isoxazolidines and we have described, the syntheses and crystal structure of, (I), 2,5-dimethyl-3-(3-methylthiophen-2-yl)-dihydro-2H-pyrrolo [3,4-d]isoxazole-4,6(5H,6aH)-dione.

The overall view and atom-labeling of the molecule of (I) are displayed in Figure 1. The hydrogen-bonding parameters are given in Table 1 and the packing arrangement of the molecules is illustrated in Figures 2–5. Compound is stabilized by intramolecular C—H···S hydrogen bond and S···N heteroatom interactions [in C1—S1···N; S···N = 2.980 (2) Å, C1—S1···N = 145.78 (17) °], which form S(4) and S(6) motifs, and intermolecular C—H···S and C—H···O hydrogen bonds and C—H···π interactions. As shown in Figures 2 and 3 the structure of the compound is made up of C8—H8···O3 and C5—H5c···S1 H-bonded polymeric bands of [C12H14N2O3S] molecules which are lined up nearly along the diagonal of the (100) (Fig. 2) and (001) (Fig. 3) planes. These polymeric C(5) chains are linked to each other and generate R44(28) ring motifs (Bernstein et al., 1995; Etter, 1990) (Fig. 4). The crystal packing is also stabilized by C12—H12c···Cg1 interactions (Fig. 5, Table 1). The dihedral angle between the succinimide and thiophen rings in [C12 H14 N2 O3 S] molecules is 46.8 (2) °.

Experimental top

N-Methyl-C-(-3-methylthiophen)nitrone was prepared from 3-methylthiophenecarbaldehyde, N-methyl-hydroxylamine hydrochloride and sodium carbonate in ethanol according to the procedure previously described (Malamidou-Xenikaki et al., 1997). This substance (3 mmol, 0.465 g) and N-methylmaleimide (3.3 mmol, 0.370 g) was dissolved in 50 ml benzene. The reaction mixture was refluxed for 9 h monitored by TLC. After evaporation of the solvent, the reaction mixture was separated by column chromatography, using mixtures of petroleum ether and ethyl acetate (1:1) as the eluant. The cis-isomer, (I), was recrystallized from CHCl3 / n-hexane (Fig. 6) (mp: 403–405 K).

Refinement top

The aromatic and methyl H atoms included in calculated positions and refined using a riding model approximation with the constrains 0.93–0.96 Å and Uiso(H) = 1.2Ueq(C) for aromatic and Uiso(H) = 1.0Ueq(C) for methyl. The methine H atoms were found in difference Fourier map and refined freely.

Special details top

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. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
