Enzymatic desymmetrization of cis-1,3-cyclohexanedicarboxylic acid diesters
摘要:
cis-1,3-Cyclohexanedicarboxylic acid (1,3-CHDA) monoesters were prepared in high overall yield and high enantiomeric purity using a three step process from cis/trans-1,3-CHDA. The asymmetry is induced by an enzymatic hydrolytic desymmetrization of a meso cis-l,3-CHDA diester. A judicious choice of ester substituents and enzyme can provide >80% overall yield of either enantiomer in >94% ee. (C) 1999 Elsevier Science Ltd. All rights reserved.
