| Abstract: | Aminophosphinyl oxides(Ⅰ ~Ⅳ) with high enantioselectivity were prepared by resolution of aminophosphinyl oxides which derived from pyrrolidine and piperidine using L-tartaric acid and L-mandelic acid as the resolution agent for the first time.Ⅰ ~Ⅳ were further applied as organic catalyst in the asymmetric hydrosilylation of N-substituted acetophenone ketimine by HSiCl3 to give chiral N-substituted-pheny amine in moderate yield and enantioselectivity. |
