Abstract Carboxylic acids, converted in situ into carboxylic-(p-nitrobenzene)sulfonic anhydrides using p-nitrobenzenesulfonyl chloride, Et3N, and DMAP in CH3CN, react with primary or secondary amines, to give amides in high yields.

Herein, we report the synthesis of substituted indolizidines and related N-fused bicycles from simple saturated cyclic amines through sequential C-H and C-C bond functionalizations. Inspired by the Norrish-Yang Type II reaction, C-H functionalization of azacycles is achieved by forming α-hydroxy-β-lactams from precursor α-ketoamide derivatives under mild, visible light conditions. Selective cleavage
在此,我们报道了通过连续的 CH 和 CC 键功能化,从简单的饱和环胺合成取代的吲哚里西啶和相关的 N-稠合双环。受 Norrish-Yang II 型反应的启发,氮杂环化合物的 CH 官能化是通过在温和的可见光条件下由前体 α-酮酰胺衍生物形成 α-羟基-β-内酰胺来实现的。使用Rh复合物选择性裂解α-羟基-β-内酰胺中的远端C(sp2)--C(sp3)键产生α-酰基中间体,该中间体经历连续的Rh催化脱羰基化,1,4加成到亲电子试剂和羟醛环化,得到包括吲哚里西啶的 N-稠合自行车。计算研究为观察到的 CC 裂解的位置选择性提供了机制上的见解,这在很大程度上取决于与膦配体的 Rh 反式结合的基团。
