Acetylation of 2-[4-(benzyloxy)-2-nitrophenyl]propane-1,3-diol with vinyl acetate in the presence of porcine pancreatic lipase gave the (R)-mono-acetate (ee = 92%). The (S)-mono-acetate was obtained via acetylation of the diol followed by transesterification in ethanol in the presence of the same enzyme. Incorporation of these opticallyactive mono-acetates into the established synthetic routes provided access
