Silver-catalyzed Regioselective Synthesis of N-aryl-1H-pyrazolyl-substituted Benzenesulfonamides from Ynamides and Pyrazoles

Silver-catalyzed N-aryl-1H-pyrazolyl substituted benzenesulfonamide derivatives were obtained regioselectively from ynamides and pyrazoles. In this intermolecular organic transformation, several substituted benzenesulfonamides were obtained in good to excellent yields by forming a new C-N bond under mild reaction conditions.
