Synthesis of Fused 1,2,3-Triazoyl-1,3,6-triazonines through Copper-Catalyzed Intramolecular Ullmann Cross-Coupling Reaction

© 2016 Elsevier Ltd We describe here an efficient method to synthesize 1-aryl-15H-dibenzo[d,h][1,2,3]triazolo[1,5-a][1,3,6]triazonines by copper-catalyzed intramolecular Ullmann cross-coupling reaction. Reactions between a range of 5-iodo-1,2,3-triazoyl benzaldehydes and substituted diaminobenzenes in the presence of a catalytic amount of CuI (5 mol %) in DMSO at 100 °C under microwave irradiation have proven to be an efficient way to access new fused 1,2,3-triazolo-1,3,6-triazonines in good to excellent yields.
