  Synthesis of 4-Aryl-1H-1,2,3-triazoles through TBAF-Catalyzed [3 + 2] Cycloaddition of 2-Aryl-1-nitroethenes with TMSN₃ under Solvent-Free Conditions

  摘要：

  TBAF-catalyzed [3 + 2] cycloaddition reactions of 2-aryl-1-cyano- or 2-aryl-1-carbethoxy-1-nitroethenes 1 with TMSN3 under SFC allow the corresponding 4-aryl-5-eyano- or 4-aryl-5-carbethoxy-1H-1,2,3-triazoles 2 to be prepared under mild reaction conditions and with good to excellent yields (70-90%). The proposed protocol does not require dried glassware or inert atmosphere.

  found to catalyse Knoevenagel condensation between aromatic aldehyde and cyano compound with active methylene hydrogens and this has led to a successful route for the one pot synthesis of 4,5-disubstituted 1,2,3-(NH)-triazoles from aldehydes through Knoevenagel-[3+2]cycloaddition-elimination sequence. In the formation of 5-aryl-2H-1,2,3-triazole-4-carbonitrile derivatives, the reaction has been found
