摘要

本文开发了一种 N-烯丙基溴二氟乙酰胺与醛的 N-杂环碳烯(NHC)催化自由基串联环化反应。该方法是合成α,α-二氟-γ-内酰胺衍生物的有效方法,收率从中等到良好(27 个实例,收率高达 88%,产率为 10 : 1 dr)。这种方法的特点是条件温和、不含金属、效率高、底物范围广。

NHC catalyzed radical tandem cyclization: an efficient synthesis of α,α-difluoro-γ-lactam derivatives†

Herein, an N-heterocyclic carbene (NHC) catalyzed radical tandem cyclization reaction of N-allylbromodifluoroacetamides and aldehydes has been developed. This method is an efficient protocol for synthesizing α,α-difluoro-γ-lactam derivatives in moderate to good yields (27 examples, up to 88% yield and 10 : 1 dr). This strategy features mild and metal-free conditions, high efficiency, and a broad substrate scope.
