  Synthetic Studies of Lepranthin, a Lichen-Produced Dimeric Macrolide. Stereoselective Synthesis of a Seco-Acid Based on Stereospecific Epoxide-Opening Reactions

  摘要：

  The stereoselective synthesis of a seco-acid derivative of lepranthin (1), a lichen-produced unique 16-membered dimeric macrolide, is described wherein all asymmetric carbon centers were constructed in a highly stereoselective manner, respectively, by using different epoxide-opening reactions of the alpha,beta-unsaturated gamma,delta-epoxy ester system and an epoxy alcohol derivative as the key steps.[GRAPHICS].
