Ternary catalysis enabled the three-component reaction of N-aryl diazoamides, aldehydes, and enamines/indoles, providing access to polyfunctionalized oxindoles in good yields with excellent diastereoselectivities and enantioselectivities (>90 examples, up to 94 % yield, 99 % ee, and >20 : 1 dr). The reaction involves the assembly of two highly reactive intermediates generated in situ by orthogonal
三元催化使 N-芳基重氮酰胺、醛和烯胺/吲哚的三组分反应成为可能,以良好的收率获得多官能化的羟吲哚,并具有出色的非对映选择性和对映选择性(>90 个例子,高达 94% 的收率,99% ee,和>20:1 博士)。该反应涉及在温和且操作简单的反应条件下通过正交催化过程原位生成的两种高反应性中间体的组装。
