(3R,6S,7aS)-3-Phenyl-6-(phenyl-sulfan-yl)perhydro-pyrrolo[1,2-c]oxazol-5-one.

ABSTRACT: Mol-ecules of the title compound [systematic name: (2R,5S,7S)-2-phenyl-7-phenyl-sulfanyl-1-aza-3-oxa-bicyclo-[3.3.0]octan-8-one], C(18)H(17)NO(2)S, form high quality crystals even though they are only packed using C-H⋯O(carbon-yl) and weak C-H⋯S inter-actions. The dihedral angle between the aromatic rings is 85.53 (5)°. The fused rings adopt envelope and twist conformations.
