enantioenriched product. Here we report a novel enantioselective double convergent 1,3-rearrangement/hydrogenation of allylic alcohols using an Ir-N,P catalyst. A variety of allylic alcohols, each consisting of a 1:1:1:1 mixture of four isomers, were converted to the corresponding tertiary alcohols with two contiguous stereogenic centers, in up to 99% ee and 99:1 d.r. DFT calculations, and control experiments suggest
对映体收敛催化有可能将起始材料的不同异构体转化为单一的高度对映体富集的产物。在这里,我们报告了一种使用 Ir-N,P 催化剂对
烯丙醇进行新型对映选择性双收敛 1,3-重排/氢化反应。各种
烯丙醇(每种均由四种异构体的 1:1:1:1 混合物组成)被转化为具有两个相邻立体中心的相应叔醇,最高ee为 99%, dr为99:1 。DFT 计算和控制实验表明,1,3-重排是反应的关键立体决定元素。
