1′′-Benzyl-1′-methyl-4′-(naphthalen-1-yl)naphthalene-2-spiro-3′-pyrrolidine-2′-spiro-3′′-indoline-1,2′′-dione

In the title compound, C38H32N2O2, the pyrrolidine ring adopts an envelope conformation, whereas the cyclohexanone ring in the tetrahydronaphthalene 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 intramolecular C—H...O close contacts and C—H...π interaction are observed. In the crystal, molecules associate via C—H...O hydrogen bonds, forming a C(12) chain motif along the ac plane
