Three-component coupling reaction of terminal alkyne, sulfonyl azide, and amine for the synthesis of N-sulfonyl amidine was developed using heterogeneous [email protected] catalyst, which was generated by pyrolysis of HKUST-1 (Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylate). A variety of terminal alkynes, sulfonyl azides, and amines underwent three-component coupling in the presence of 5 mol % [email protected]
