چکیده
In the title compound, C(38)H(32)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 benzyl ring is oriented at an angle of 67.1 (1)° with respect to the naphthyl ring system. Four intra-molecular C-H⋯O close contacts and C-H⋯π inter-action are observed. In the crystal, mol-ecules associate via C-H⋯O hydrogen bonds, forming a C(12) chain motif along the ac plane.
