ABSTRACT: In the title compound, C(32)H(28)N(2)O(2), the pyrrolidine ring adopts an envelope conformation, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene fused-ring system adopts a half-chair conformation. The oxindole ring system is oriented at an angle of 48.2 (1)° with respect to the naphthyl ring system. An intra-molecular C-H⋯O close contact is observed. In the crystal, mol-ecules associate via two C-H⋯O hydrogen bonds, forming R(2) (2)(14) and R(2) (2)(10) dimers.
