In the title compound, C39H38N2O4, the pyridinone ring adopts a twisted half-chair conformation with the N atom deviating by 0.3304 (1) and with the methylene C atom adjacent to the octahydroindolizine unit deviating by 0.444 (3) Å from the mean plane defined by the other four atoms. In the octahydroindolizine system, the pyrrolidine ring exhibits an envelope conformation, with the fused methyne C atom deviating by 0.6315 (1) Å from the mean plane defined by the other four atoms, and the piperidine ring exhibits a distorted chair conformation, as reflected in the puckering parameters Q = 0.568 (4) Å, = 1.5 (4) and = 161 (16)°. In the crystal pairs of weak C-HO interactions form centrosymmetric dimers, which are further connected by C-H interactions. The crystal studied was a non-merohedral twin, with a domain ratio of 0.91:0.09.
