Abstract

AbstractAn efficient microwave‐assisted synthesis of tertiary propargylamines has been developed by copper(I)‐catalyzed decarboxylative A3‐coupling reaction of an alkynylcarboxylic acid with a secondary amine and an aldehyde. A wide range of diversely substituted propargylamines could be synthesized in high yields. The optimal reaction conditions are also effective for 3‐alkylpropiolic acids and for terminal propiolic acid.
