The enantioselective carbene insertion into N–H bonds of anilines has been realized by cooperative catalysis of ruthenium complexes and chiral phosphoric acids, providing the expected α-aryl glycines in moderate to good yields with high enantioselectivity. Typically, by slightly modifying the reaction conditions, this approach allows the N–H bond insertion reaction to be effective for both α-aryl and
通过钌络合物和手性磷酸的协同催化,实现了对苯胺 N-H 键的对映选择性卡宾插入,以中等至良好的产率和高对映选择性提供了预期的 α-芳基甘氨酸。通常,通过稍微修改反应条件,该方法首次使 N-H 键插入反应对 α-芳基和 α-烷基重氮乙酸酯均有效,且具有高对映选择性(分别高达 96% 和 95% ee) )。
