Copper-Catalyzed One-Pot Synthesis of <em>N</em>-Sulfonyl Amidines from Sulfonyl Hydrazine, Terminal Alkynes and Sulfonyl Azides
<i>N</i>-Sulfonyl amidines are developed from a Cu-catalyzed three-component reaction from sulfonyl hydrazines, terminal alkynes and sulfonyl azides in toluene at room temperature. Particularly, the intermediate <i>N</i>-sulfonylketenimines was generated via a CuAAC/ring-open...
