Deskripsi
In the title compound, C32H28N2O2, the pyrrolidine ring adopts an envelope conformation, whereas the cyclohexanone ring in the tetrahydronaphthalene 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 intramolecular C—H...O close contact is observed. In the crystal, molecules associate via two C—H...O hydrogen bonds, forming R22(14) and R22(10) dimers.
