The first total syntheses of two alpha,beta-unsaturated glactones having a
1,3-syn-polyol moiety, isolated from Cryptocarya latifolia, were achieved.
The key reactions include the Sharpless asymmetric epoxidation of the allyl
alcohol, stereoselective addition of an allyl group to the epoxy aldehyde,
regioselective reduction of the epoxy ring, and formation of the alpha,bet
a-unsaturated delta-lactone. (C) 1999 Elsevier Science Ltd. All rights rese
