Copper-catalyzed Larock-type cyclization/debenzylation of yne-allylic esters with aliphatic amines

引用

Science China Chemistry 2025年

作者： Rongkang Huang Yuepeng Lu Feng Xu Jianhang Huang Cuiju zhu hao Xu Engineering Research Center of Photoenergy Utilization for Pollution Control and Carbon Reduction State Key Laboratory of Green Pesticide College of Chemistry Central China Normal University

Herein, we describe a strategy for constructing pyrroles via a copper-catalyzed [4 + 1] annulation of yne-allylic esters and aliphatic amines. The key innovation of this approach is the development of copper-ammonium intermediates that facilitate selective C–N bond cleavage under mild conditions. This method demonstrates broad applicability, accommodating both aliphatic secondary amines and aliphatic primary amines, while exhibiting excellent tolerance toward a wide range of functional groups. Furthermore, the ease of subsequent transformations underscores its potential utility in the synthesis of bioactive compounds. Preliminary mechanistic investigations suggest the involvement of a copper-ammonium species, providing insight into the reaction's underlying process.
