Applications of Biotransformations in Organic Synthesis: Preparation of Enantiomerically Pure Esters of cis- and trans-Epoxysuccinic Acid

Chemical and enzymatic procedures have been investigated for the resolution of esters of trans-epoxysuccinic acid (trans-oxirane-2,3-dicarboxylic acid).A successful resolution was achieved by transesterification of the diethyl ester against heptanol catalysed by the lipase from Rhizopus javanicus.Asymmetrization of cis-epoxysuccinic acid was achieved by enantioselective and regiospecific hydrolysis of the racemic diethyl ester of 2-(toluene-p-sulfonyloxy)tartaric acid , followed by esterification with 2-methylpropanol and oxirane formation.
