发展了手性路易斯碱催化的2-位无取代基的二芳基甲酮亚胺的不对称氢化硅烷化反应,在20 mol%的最优催化剂催化下,以良好的收率(最高达97%)和中等到良好的对映选择性(最高达89%)获得了一系列手性二芳基甲胺类化合物,并通过单晶X射线衍射的方法确定了其中一个反应产物的绝对构型.
The asymmetric hydrosilylation of the 2-position unsubstituted diarylmethanone imine catalyzed by chiral Lewis base was developed with good yield (up to 97%) under the optimum catalyst catalysis of 20 mol% %) And moderate to good enantioselectivity (up to 89%) obtained a series of chiral diarylmethylamine compounds and determined by single crystal X-ray diffraction method of one of the absolute configuration of the reaction product .
