The catalytic asymmetric construction of silicon‐stereogenic silanes is of great interest and significance, but has met with only limited success to date. We herein report the enantioselective hydrosilylation of alkenes with dihydrosilanes by a chiral half‐sandwich scandium catalyst, which constitutes an efficient and general route for the synthesis of a wide range of enantioenriched silicon‐stereogenic
固硅硅烷的催化不对称结构具有极大的意义和意义,但迄今为止仅取得了有限的成功。我们在此报告了通过手性半三明治scan催化剂与二氢硅烷进行烯烃的对映选择性氢化硅烷化反应,这是从易于获得的起始原料合成各种对映体富集的硅立体异构硅烷的有效且通用的途径。该反应具有广泛的底物范围,高收率和高对映选择性的特征。一些手性叔硅烷产物也被转化为有价值的衍生物,例如手性硅烷醇,季硅烷和苯甲酚化合物。
