(3R,3aS,6aR)-2,5-Dimethyl-3-(5-phenyl-2-thien-yl)perhydro-pyrrolo[3,4-d][1,2]oxazole-4,6-dione.

The crystal structure of the title compound, C(17)H(16)N(2)O(3)S, exhibits intra-molecular C-H⋯S and inter-molecular C-H⋯S and C-H⋯O hydrogen bonds, C-S⋯N [S⋯N = 3.033 (2) Å and C-S⋯N = 142.76 (9)°] inter-actions, and C-H⋯π inter-actions; these inter-actions 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) Å from the plane of the other ring atoms. The thio-phene ring is oriented with respect to the succinimide and phenyl rings at dihedral angles of 40.03 (12) and 5.21 (13)°, respectively. The dihedral angle between the succinimide and phenyl rings is 39.38 (12)°.
