Abstract
A mild and stereoselective gold(I)-catalyzed domino transformation of propargylic esters leading to substituted (1E,3E)-dienes has been developed. This cascade process proceeds via a sequence of 1,3-acyloxy- or 1,3-phosphatyloxy migrations to form allenic intermediate followed by a proton transfer.
摘要
已开发出一种温和且立体选择性的金（I）催化的炔丙基酯多米诺转化反应，可生成取代的（1E，3E）-二烯。该串联过程通过1,3-酰氧基或1,3-磷酸氧基迁移序列进行，以形成烯丙基中间体，随后进行质子转移。
