Isopropyl 1-benzoyl-4-benzo­yloxy-2,6-di­phenyl-1,2,3,6-tetrahydropyridine-3-carboxyl­ate

In the title compound, C₃₅H₃₁NO₅, the piperidine ring has an envelope conformation, with the phenyl-substituted C atom adjacent to the methyl­ene C atom as the flap. This flap atom deviates by 0.633 (2) Å from the mean plane of the other five essentially coplanar atoms in the ring (r.m.s. deviation = 0.044 Å). Intra­molecular C—H...O hydrogen bonds form S(7) and S(9) ring motifs. In the crystal, mol­ecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers with R²₂(16) loops.
