1-Formyl-r-2,c-6-bis(4-methoxyphenyl)-t-3,t-5-dimethylpiperidin-4-one

Abstract

In the title compound, C22H25NO4, the piperidine ring adopts a distorted boat conformation. The methyl groups at the 3 and 5 positions of the piperidine ring are in axial and equatorial orientations, respectively. Both H and O atoms in the aldehyde group are disordered over two positions with occupancies of 0.534 (5) and 0.466 (5). In the crystal, the molecules are linked into a three-dimensional network by C—H...O hydrogen bonds.
