Crystal and molecular structures of 2,4-diacetyl-5-hydroxy-5-methyl-3-phenyl-N-benzyl-1-cyclohexenylamine

2,4-Diacetyl-5-hydroxy-5-methyl-3-phenyl-N-benzyl-1-cyclohexenylamine is obtained by benzylamination of 2,4-diacetyl-5-hydroxy-5-methyl-3-phenylcyclohexanone. Based on spectral and X-ray structural data, the half-chair conformation of the cyclohexenyl ring and the pseudoequatorial orientation of all substituents, except for the pseudoaxial OH-group, are established. An intramolecular hydrogen bond N-H...O=C is revealed.
