摘要
The pH dependence of the .alpha.-chymotrypsin-catalyzed hydrolysis of dimethyl 3-hydroxyglutarate (3) has been studied. The e.e. was determined by HPLC analysis of diastereoisomeric camphanoic-acid derivatives. Kinetic resolution of the .beta.,.gamma.-epoxy esters 10 and 24 by pig liver esterase has been shown to provide an alternative access to chiral .beta.-hydroxy esters and acids of high optical purity. By this latter method, the unnatural enantiomer of .gamma.-amino-.beta.-hydroxybutyric acid (GABOB) has been synthesized. Finally, dimethyl meso-3,4-epoxyadipate (19) was hydrolyzed by pig liver esterase with almost 100% selectivity.
