propargylamines has been developed by copper(I)-catalyzeddecarboxylative A3-coupling reaction of an alkynylcarboxylic acid with a secondaryamine 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 propiolicacid.

was found to be a highly effective catalyst for the three-componentcoupling reactions of aldehydes, alkynes, and amines (A3-coupling) via C−H activation. The reactions could be applied to both aromatic and aliphatic aldehydes and alkynes. Nearly quantitative yields of the desired products were obtained in most cases. No cocatalyst or activator is required, and water is the only byproduct in the reactions
