In the title compound, C21H24N2O3S2, the three five-membered rings adopt envelope conformations. The dihedral angle between the two aromatic rings is 68.4 (1)°. C—H...O inter­actions link the mol­ecules into a chain and the chains are cross-linked via C—H...π inter­actions involving the meth­oxy­phenyl ring.

Comment top

Substituted pyrrolidine compounds have gained much importance as they are the structural elements of many alkaloids. The pyrrolidine derivatives have been found to possess antifungal activity against various pathogens (Amal Raj et al., 2003). Thiazolidine derivatives may act as potent inhibitors specific for Pro1yl Endopeptidase (Tsuru et al., 1988). In view of the above facts, we have undertaken the X-ray crystal structure determination of the title compound.

Bond lenghts and angles in the title molecule (Fig. 1) are comparable to those observed in a related structure (Kavitha et al., 2006). The sums of the bond angles around N1 (343.7°) and N2 (333.1°) indicate sp3-hybridization. The thiazolidine and the two pyrrolidine rings (N1/C1—C4, A, and C2/C3/N2/C5/C6, B) adopt envelope conformations. Atom N1 in ring A lies 0.597 (2) Å below the C1—C4 mean plane and atom C6 in ring B lies 0.563 (3) Å above the N2/C3/C2/C5 plane. In the thiazolidine ring, atom C6 deviates by 0.554 (3) Å from the plane of the rest of the atoms in the ring. The puckering parameters (Cremer & Pople, 1975) and the smallest displacement asymmetry parameters (Nardelli, 1983) are q2 = 0.406 (2) Å, ϕ = 187.3 (3)° and Δs(N1) = 6.5 (2)° for ring A, q2 = 0.372 (2) Å, ϕ = 137.0 (3)° and Δs(C6) = 4.2 (2)° for ring B, and q2 = 0.378 (2) Å, ϕ = 69.8 (3)° and Δs(C6) = 3.7 (2)° for the thiazolidine ring. The dihedral angle between the two aromatic rings is 68.4 (1)°.

The crystal packing is stabilized by C—H···O and C—H···π intermolecular interactions.

Experimental top

A mixture of 2-(N-allyl-N-phenylsulfonyl) butanal (1.0 mmol) and of 2-p-methoxyphenylthiazolidine-4-carboxylic acid (1.5 mmol) in dry toluene (30 ml) was refluxed under Dean-Stark conditions till the completion of the reaction (3 h). The reaction mixture was then concentrated under reduced pressure. The residue was extracted with dichloromethane (2× 20 ml) and water (2× 20 ml). The organic layer was washed with brine solution (2× 20 ml), dried over anhydrous sodium sulfate and concentrated in vacuum. The residue was then subjected to column chromatography (silica gel, 100–200 mesh) with hexane-ethylacetate (8:2) to obtain the cycloadduct. Single crystals were obtained by recrystallization from methanol.

Refinement top

H atoms were included in calculated positions and treated in the subsequent refinement as riding atoms, with C—H = 0.93–0.98 Å and Uiso(H) = 1.2–1.5(methyl) Ueq(C).

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.
