9,9-Dimethyl-12-(3-nitrophenyl)-7,8,9,10,11,12-hexahydrobenz[a]acridin-11-one

Abstract

The title compound, C25H22N2O3, was synthesized by the reaction of 3-nitro­benzaldehyde, dimedone and 2-naphthyl­amine in ethanol. In the mol­ecular structure, the cyclo­hexenone ring adopts an envelope conformation, whereas the piperidine ring has a boat conformation. The crystal packing is stabilized by inter­molecular N—H⋯O hydrogen bonds.
