Abstract

An efficient and enantiocontrolled total synthesis of natural (-)-xanthorrhizol (3) has been accomplished by employing the lipase-mediated asymmetric acetylation of the σ symmetrical prochiral 2-ary-1,3-propanediol (7) leading to the formation of the opically enriched monoacetate (6) as the key step.
