[reactions: see text] Intramolecular additions of hydroxyl or carboxyl groups to inert olefins catalyzed by simple silver(I) triflate are described. Good to excellent yields can be obtained for a range of substrates under relatively mild conditions. This reaction represents one of the simplest methods to construct cyclic ethers or lactones.
[反应:见正文] 描述了由简单的三氟甲磺酸银(I)催化的羟基或羧基对惰性烯烃的分子内加成反应。在相对温和的条件下,一系列底物都能获得良好至优异的产率。该反应是构建环醚或内酯的最简单方法之一。
