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.

The first copper-catalyzed direct three-componentcoupling reaction of aldehydes, alkynes, and hydroxylamines for the synthesis of propargylamines has been developed under mild conditions, which has the advantages of ready availability of catalyst as well as operation simplicity. The present protocol provides an appealing alternative for the construction of propargylamines in a simple and one-pot procedure

A tri‐umph in many respects: The iron‐catalyzed ligand‐free, one‐pot three‐componentcoupling reactions of aldehydes, terminal alkynes, and amines in the presence of 4 A molecular sieves yields the corresponding propargylamines in good to excellent yields, displays a broad substrate scope, and is economical and environmentally friendly (see scheme).

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
