ABSTRACT
In the title compound, C(39)H(38)N(2)O(4), the pyridinone ring adopts a twisted half-chair conformation with the N atom deviating by 0.3304 (1) and with the methyl-ene C atom adjacent to the octa-hydro-indolizine unit deviating by 0.444 (3) Å from the mean plane defined by the other four atoms. In the octa-hydro-indolizine 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, θ = 1.5 (4) and ϕ = 161 (16)°. In the crystal pairs of weak C-H⋯O inter-actions form centrosymmetric dimers, which are further connected by C-H⋯π inter-actions. The crystal studied was a non-merohedral twin, with a domain ratio of 0.91:0.09.
