Abstract

A reaction of (±)-(E)-1-(2-furyl)but-2-en-1-ol (1) under the Sharpless asymmetric oxidation condition using 30 mol% of D-(-)-diisopropyl tartrate (DIPT), 25 mol% of titanium tetraisopropoxide and 120 mol% of tert-butyl hydroperoxide (TBHP) afforded the (S)-epoxide (3), in 42% yield with high optical purity, which was further converted into an antitumour antibiotic, asperlin (10).
