rac-Diethyl 6-hy­droxy-4-(2-hy­droxy­eth­yl)amino-6-methyl-2-phenyl­cyclo­hex-3-ene-13-dicarboxyl­ate

摘要

The title compound, C21H29NO6, is chiral with three stereogenic centres. The crystal is a racemate and consists of enanti­omeric pairs with the relative configuration rac-(2R*,3S*,4R*). The ethyl fragment of the eth­oxy­carbonyl group at position 1 is disordered in a 0.60:0.40 ratio. The crystal packing displays inter­molecular O—H⋯O hydrogen bonding. An intra­molecular N—H⋯O hydrogen bond also occurs.
