[reaction: see text] A general method is described for the direct and stereoselective synthesis of epoxypolyenes via Suzuki-Miyaura cross-coupling reaction of 1-iodoalkenes with B-alkylboron compounds. It allows for the straightforward and convergent assembly of compounds that are structurally similar to (3S)-oxidosqualene, an important intermediate in steroid biosynthesis.
[反应:见正文]描述了一种通过1-碘代烯烃与B-烷基硼化合物的Suzuki-Miyaura交叉偶联反应直接和立体选择性合成环氧多烯的通用方法。它使结构类似于(3S)-氧化角鲨烯(类固醇生物合成中的重要中间体)的化合物能够直接且会聚地组装。
