(3R, 3aS, 6aR)-2,5-Dimethyl-3-(5-phenyl-2-thienyl)perhydropyrrolo[3,4-d][1,2]-oxazole-4,6-dione

Abstract

The crystal structure of the title compound, C17H16N2O3S, exhibits intramolecular C-H center dot center dot center dot S and intermolecular C-H center dot center dot center dot S and C-H center dot center dot center dot O hydrogen bonds, C-S center dot center dot center dot N [S center dot center dot center dot N = 3.033 (2) angstrom and C-S center dot center dot center dot N = 142.76 (9)degrees] interactions, and C-H center dot center dot center dot pi interactions; these interactions generate S(4), S(6) and R-2(2)(14) ring motifs. The isoxazole ring adopts an envelope conformation, with the N atom displaced by 0.672 (2) angstrom from the plane of the other ring atoms. The thiophene ring is oriented with respect to the succinimide and phenyl rings at dihedral angles of 40.03 (12) and 5.21 (13)degrees, respectively. The dihedral angle between the succinimide and phenyl rings is 39.38 (12)degrees.
