  Total syntheses of four possible stereoisomers of resolvin E3

  摘要：

  Resolvin E3, 17,18-dihydroxy-5Z,8Z,11Z,13E,15E-eicosapentaenoic acid, is a potent anti-inflammatory lipid mediator. To determine the stereochemistries of the C17- and C18-hydroxy groups of resolvin E3 and to supply a sufficient amount of material for future biological studies, we developed a highly convergent and practical route to its four possible stereoisomers. The key reactions employed here were the Horner-Wadsworth-Emmons coupling, the two copper(I)-mediated reactions between the alkynes and the propargyl tosylates, and the simultaneous reduction of the three triple bonds to the three Z-olefins.

  The four stereoisomers of novel lipid mediator 1, (5Z,8Z,10E,14Z)-12-hydroxy-17,18-epoxy-5,8,10,14-eicosatetraenoic acid, were synthesized from six simple fragments. Triyne 2 was convergently assembled through three SN2 alkynylation reactions and one Sonogashira coupling reaction. Two of the three alkynes of 2 were hydrogenated using Lindlar catalyst, while the third alkyne was reduced through formation

  The enantioselective synthesis of (−)-α-conhydrine has been achieved by two different synthetic routes. The key steps include Sharpless asymmetric dihydroxylation, regioselective opening of a cyclic sulfate and Wittig olefination.

  （-）-α-conhydrine的对映选择性合成已通过两种不同的合成途径实现。关键步骤包括Sharpless不对称二羟基化，环状硫酸盐的区域选择性开环和Wittig烯烃化。
