hydrosilylation of a vast array of aryl cycloalkyl ketones with different ring sizes was studied systematically for the first time (up to 99% enantiomeric excess). The results demonstrated that the steric size of cycloalkyl groups has a significant influence on the reaction outcomes. The first stereoselective formation of a selection of cyclohexyl heteroaryl alcohols of up to 97% enantiopurity was realized
首次系统地研究了非贵金属铜催化的各种不同环尺寸的芳基环烷基酮的对映选择性氢化硅烷化(对映体过量高达99%)。结果表明,环烷基的空间大小对反应结果有重要影响。还实现了对映体纯度高达97%的环己基杂芳基醇的选择的首次立体选择性形成。在某些环己基吡啶基酮的还原中,观察到温度对醇产物的对映体纯度和绝对构型都有显着影响。
