The influence of the alcohol, as the hydrogen donor, on the efficiency and selectivity of the asymmetric transfer hydrogenation (ATH) of imines is reported for the first time. This discovery not only leads to a highly enantioselective access to N‐aryl and N‐alkyl amines, but also provides new insight into the mechanism of the ATH of imines. Both experimental and computational studies provide support
首次报道了作为氢供体的醇对亚胺的不对称转移氢化(ATH)的效率和选择性的影响。这一发现不仅导致对N-芳基和N-烷基胺的高度对映选择性,而且为亚胺ATH的机理提供了新的见解。实验研究和计算研究均为涉及铱醇盐作为还原物种的反应途径提供了支持。
