Abstract: In the title compound, C₃₇H₃₂N₂O₃, an intramolecular O-HN hydrogen bond generates a five-membered ring, producing an S(5) motif. The piperidone ring adopts a half-chair conformation. The two fused pyrrolidine rings have similar envelope conformations. The interplanar angles between the benzene rings A/B and C/D are 75.68 (7) and 30.22 (6)°, respectively. In the crystal structure, adjacent molecules are interconnected into chains propagating along the [010] direction via intermolecular C-HO hydrogen bonds. Further stabilization is provided by weak C-H interactions.
