Crystal structure of 1-{3-acetyl-2-(4-chlorophenyl)-6-hydroxy-4-[(2-hydroxypropyl)amino]-6-methylcyclohex-3-en-1-yl}ethanone

Abstract

In the title compound, C20H26ClNO4, the central cyclohexene ring adopts an approximate envelope conformation with the C atom binding with the hydroxy group at the tip of the flap. There is an intramolecular N - H⋯O hydrogen bond generating an S(6) ring motif. In the crystal, classical O - H⋯O hydrogen bonds and weak C - H⋯O and C - H⋯Cl interactions link the molecules, forming a three-dimensional supramolecular architecture. The crystal structure was refined as a four-component twin.
