Triazoles are an important class of heterocyclic compounds. In recent years 1,2,3-triazoles gained more and more interest due to their diverse biological activities and synthetic methodology [1 – 3]. An efficient approach for constructing the 1,2,3-triazole unit is the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, which was discovered independently by the groups of Sharpless ...
