A one-pot reaction for the transformation of common secondary amides into amines with C–C bond formation is described. This method consists of in situ amide activation with Tf2O–partial reduction–addition of C-nucleophiles. The method is general in scope, which allows employing both hard nucleophiles (RMgX, RLi) and soft nucleophiles, as well as enolates. With the use of soft nucleophiles, the reaction
描述了一锅反应,可将常见的仲酰胺转化为具有C-C键的胺。该方法包括的原位酰胺活化与TF 2 O形部分还原加成的Ç -nucleophiles。该方法的范围很广,可以同时使用硬亲核试剂(RMgX,RLi)和软亲核试剂以及烯醇盐。使用软的亲核试剂,在酯,氰基,硝基和叔酰胺基团存在的情况下,反应在仲酰胺上以高化学选择性进行。
