Direct oxidation of racemic beta-hydroxyketones 1a-c under Sharpless oxidation conditions resulted in the enantiomeric alpha,beta-dihydroxyketones 2a in 97% ee, 2b in 86% ee and 29 in 95% ee respectively, in 37-58% of isolated yield. The oxidation is assumed to proceed via an allylic enolate intermediate. (C) 1997 Elsevier Science Ltd.
