Copper(I)-Catalysed Deacetylenative Cross-Coupling Reaction of Terminal Alkynes with Propargylic Amines via C(sp)-C(sp3) Bond Cleavage
摘要:
The catalytic deacetylenative coupling reaction of terminal alkynes with various N-substituted propargylic amines proceeded in the presence of CuCl (10 mol%) and Na2HPO4 (4 equiv) in THF at 130 degrees C to give the corresponding substituted propargylic amines in good to high yields.

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.
