5′′-(4-Chloro­benzyl­idene)-1′-(4-chloro­phen­yl)-1′′-methyl-1′,2′,3′,5′,6′,7′,8′,8a'-octa­hydro­dispiro­[acenaphthyl­ene-1,3′-indolizine-2′,3′′-piperidine]-2,4′′(1H)-dione

In the title compound, C₃₇H₃₂Cl₂N₂O₂, the pyridinone ring adopts a twisted half-chair conformation. The fused pyrrolidine and piperidine rings of the octa­hydro­indolizine unit exhibit envelope (with the C atom bound to the C atom bearing the chloro­benzene ring being the flap atom) and chair conformations, respectively. The dihedral angle between the chloro­benzene rings is 84.03 (1)°. In the crystal, C—H...π inter­actions lead to supra­molecular chains along [101] that assemble in the ac plane. Connections along the b axis are of the type Cl...Cl [3.4065 (8) Å].

2-Hy­droxy-5-[(E)-2-methyl­benzyl­idene]-8-(2-methyl­phen­yl)-9-phenyl-3,10-diaza­hexa­cyclo­[10.7.1.1^3,7.0^2,11.0^7,11.0^16,20]henicosa-1(20),12,14,16,18-pentaen-6-one

In the title compound, C₄₀H₃₄N₂O₂, the central piperidine ring adopts a half-chair conformation and the fused pyrrolidine rings adopt twisted envelope (with the C atom bearing the methylphenyl ring as the flap atom) and envelope (with the C atom bound to the N atom, common to the pyridinone and pyrrolidine rings being the flap atom) conformations. The mol­ecular structure features weak intra­molecular N—H...O and C—H...O inter­actions. In the crystal, O—H...O hydrogen bonds generate a C(7) chain along the b-axis direction. C—H...O inter­actions also occur.
