Abstract: In the title compound, C₃₄H₃₀N₂O₂, the pyrrolidine and piperidinone rings each adopt a half-chair conformation. The dihedral angle between the two phenyl-ring substituents is 70.4  (1)°. Intramolecular C-HO hydrogen bonds are observed in the crystal structure. In addition to these interactions, C-H interactions also play a role in stabilizing the crystal structure.
