Regio- and stereoselective hydrostannylation of alkyl ethynyl ethers generates alkenyl ethers, which are useful building blocks in organic synthesis. This efficient synthetic method, however, is limited. Here, we report not only an efficient method for a highly regio- and stereoselective Pd-catalyzed hydrostannylation of alkyl ethynyl ethers but also a scalable synthesis and construction of the core
烷基乙炔基醚的区域和立体选择性加氢苯乙烯基化反应生成烯基醚,这是有机合成中有用的组成部分。但是,这种有效的合成方法受到限制。在这里,我们不仅报告了一种高效的方法,用于烷基乙炔基醚的高度区域选择性和立体选择性的Pd催化加氢苯乙烯基化反应,而且还报道了具有所有功能基团和立体中心的luminamicin核心框架的可扩展合成和构建。
