transfer (HAT) catalyst, provides a directsynthesis of α‐tertiary amines, or their corresponding γ‐lactams. We anticipate that this methodology will inspire new retrosynthetic disconnections for substituted amine derivatives in organicsynthesis, and particularly for challenging α‐tertiary primaryamines.

An attractive strategy for the synthesis of saturated nitrogen-containing heterocycles is described herein, involving the implementation of ruthenium-catalyzed intramolecular hydrocarbamoylation of olefins. The process proceeds by formal C-H bond cleavage of an allylic formamide followed by construction of a new C-C bond in a reaction that is characterized by complete atom-economy. The method is particularly
本文描述了一种合成饱和含氮杂环的有吸引力的策略,包括实施钌催化的烯烃分子内烃甲酰化。该过程通过烯丙基甲酰胺的正式 CH 键裂解进行,然后在以完全原子经济为特征的反应中构建新的 CC 键。该方法与许多可用于制备旋光烯丙基甲酰胺的有效策略相结合特别有价值。
