title: Crystal structure of 1-{3-acetyl-2-(4-chloro-phen-yl)-6-hy-droxy-4-[(2-hy-droxy-prop-yl)amino]-6-methyl-cyclo-hex-3-en-1-yl}ethanone.
abstract: In the title compound, C20H26ClNO4, the central cyclo-hexene ring adopts an approximate envelope conformation with the C atom binding with the hy-droxy 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 inter-actions link the mol-ecules, forming a three-dimensional supra-molecular architecture. The crystal structure was refined as a four-component twin.
