Methyl 4-(benzylamino)-6-methyl-2-oxo-3-cyclohexene-1-carboxylate, C16H19NO3

Abstract

The cyclohexene ring adopts an almost ideal sofa conformation. The bond lengths of the C---C--C--O fragment indicate strong conjugation through these bonds. Other planar fragments of the molecule, i.e. the phenyl ring and the ester group, make angles of 60.82 (4) and 75.20 (6) °, respectively, with the plane of the cyclohexene ring. The methyl substituent occupies an equatorial position. In the crystal structure, the intermolecular N--H...O hydrogen bonds form infinite chains of molecules along the [010] direction.
