[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]描述了在简单的三氟甲磺酸银(I)催化下将羟基或羧基分子内加成至惰性烯烃。在相对温和的条件下,对于一定范围的基材,可以获得良好或优异的产量。该反应代表构建环醚或内酯的最简单方法之一。
