Herein, an N-heterocyclic carbene (NHC) catalyzed radical tandem cyclization reaction of -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.
在此，已开发出一种N-杂环卡宾（NHC）催化的烯丙基溴二氟乙酰胺与醛的自由基串联环化反应。该方法是一种以中等至良好产率合成α,α-二氟-γ-内酰胺衍生物的有效方案（27个实例，产率高达88%，非对映选择性为10:1）。该策略具有温和、无金属条件、高效率和广泛的底物范围等特点。
