T-3-Benzyl-1-formyl-r-2,c-6-diphenylpiperidin-4-one

Abstract

The piperidine ring of the title compound, C25H23NO2, is in a distorted boat form. The phenyl ring at position 2 makes a dihedral angle of 80.6 (1)° with the phenyl ring of the benzyl group at position 3, and 61.2 (1)° with the phenyl ring at position 6. The dihedral angle between the phenyl ring of the benzyl group and the phenyl ring at position 6 is 84.2 (1)°. The formyl group and the phenyl ring at position 6 have equatorial orientations. The phenyl ring at position 2 and the benzyl group at position 3 have axial orientations. C—H⋯O and C—H⋯π hydrogen bonds are found in the crystal structure.
