چکیده
In the title mol-ecule, C(27)H(24)N(2)O(2), the pyrrolidin-2-one ring is almost planar (r.m.s. deviation = 0.003 Å), the pyrrolidine ring has an envelope conformation (the N atom is the flap atom) and the cyclo-penta-none ring is twisted about the C(q)-C(m) bond (q = quaternary and m = methylene). The ketone O atoms are directed to opposite sides of the mol-ecule. Supra-molecular chains along the a axis are formed in the crystal packing mediated by N-H⋯N and C-H⋯O inter-actions. These are connected into layers in the ab plane via C-H⋯π inter-actions.
