title: 2-[(1RS,3RS,3aRS,6aSR)-5-Benzyl-4,6-dioxo-3-phenyl-octa-hydro-pyrrolo-[3,4-c]pyrrol-1-yl]acetamide.
abstract: In the title compound, C(21)H(21)N(3)O(3), the relative stereochemistry of the four stereogenic C atoms has been determined. The dihedral angle between the phenyl rings is 77.63 (7)°. In the crystal, ribbons spread along the a axis are formed by N-H⋯O hydrogen bonds. C-H⋯π inter-actions also occur.
