Abstract

A three-step sequence involving highly stereoselective deconjugation of ethyl (E)-2-pentenoate, osmylation, and resolution by lipase-catalyzed enzymatic acetylation allowed an extremely expeditious synthesis of (3R,4S)-3-hydroxy-4-methyl-γ-butyrolactone with 90% ee, from which (—)-blastmycinolactol and (+)-blastmycinone were synthesized.
