A strategy for the synthesis of chiral 5-(1-hydroxyalk-2-enyl)-5H-furan-2-ones and its application to the total synthesis of (-)-muricatacin, in four steps and 37% overall yield from (R,R)-hexa-1,5-diene-3,4-diol, are described. The key synthetic step in this approach is a highly regioselective and stereoselective tandem ring-closing/cross metathesis reaction in which both lactone formation and alkyl
合成手性5-(1-羟基烷-2-烯基)-5H-呋喃-2-酮的策略及其在(-)-毛里卡他星全合成中的应用,分四个步骤进行,从(描述了R,R)-六-1,5-二烯-3,4-二醇。该方法中关键的合成步骤是高度区域选择性和立体选择性串联闭环/交叉复分解反应,其中内酯的形成和烷基链的延伸均通过有效的一锅法完成。
