lenol, can be utilized for the synthesis of several important core structures. In this work, a method is developed for the diastereoselective synthesis of spirocyclic ethers using a silver catalyst under the presence of acid. This protocol can be applied to a variety of substrates resulting in the corresponding products in 35–97% yields with good diastereoselectivity. The proposed reaction mechanisms
邻-羰基芳基乙炔醇,可用于合成几个重要的核心结构。在这项工作中,开发了一种在酸存在下使用银催化剂非对映选择性合成螺环醚的方法。该协议可应用于各种底物,以 35–97% 的产率获得相应的产品,并具有良好的非对映选择性。使用 DFT 计算研究了相应产物的拟议反应机制和立体选择性结果。此当前协议可应用于广泛的底物,这将有助于创建螺环醚库
