Abstract

In the title compound, C(29)H(23)NO(2), the pyrrolidine ring adopts a twisted conformation about one of the C-N bonds. The acenaphthone ring (r.m.s. deviation = 0.025 Å) lies almost perpendicular to the pyrrolidine ring [dihedral angle = 88.08 (8)°]. The dihedral angle between the phenyl rings is 88.12 (11)°. In the crystal structure, weak C-H⋯π inter-actions connect the mol-ecules.
