species comprising N-sulfinyl and N-sulfonyl ketimine, oxime, and enamine derivatives were subjected to asymmetric transfer hydrogenation in an azeotropic mixture of formic acid/triethylamine. Among them, the Rh-catalyzed transfer hydrogenation of N-sulfonyl ketimine afforded the corresponding 1-arylalkylamines in excellent yield and with high enantioselectivity.
在甲酸/三乙胺的共沸混合物中,将包含N-亚磺酰基和N-磺酰基酮亚胺,肟和烯胺衍生物的几种亚胺类化合物进行不对称转移氢化。在它们之中,Rh催化的N-磺酰基酮亚胺的转移氢化以优异的产率和高的对映选择性提供了相应的1-芳基烷基胺。
