Chiral carbamates through an enzymatic alkoxycarbonylation reaction.
摘要:
Chiral carbamates could be obtained by enzymatic alkoxycarbonylation with vinyl carbonates and racemic amines using Candida antarctica lipase. The enantioselectivity achieved depended on the substrate nature and the solvent.

Carbonates could be obtained by enzymatic alkoxycarbonylation from vinyl carbonates, which are easily prepared from vinyl chloroformate. The reaction was catalyzed by Candida antarctica lipases, SP 435 and SP 435 A. The method could be also used for the synthesis of carbamates. When racemic alcohols were used, lipase catalyzed their resolution, and chiral carbonates were obtained with different enantiomeric excesses depending upon the structure of the alcohol.
