Highly enantioselective enzymatic resolution of cis-fused octalols mediated by Candida antarctica lipase (Novozym 435)
摘要:
Optically active cis-fused octalin acetates have been prepared by esterification of cis-fused octalols using Candida antarctica lipase (CALB-Novozym 435). The enzyme efficiently resolved the racemic octalols by kinetic resolution, to afford cis-fused octalols and cis-fused octalin acetates with high enantiomeric excesses (up to > 99%) and good yields (> 40%).
