It has been shown that various pyrido-, quinolino-, pyrazino-, and quinoxalinotetrazoles can be used efficiently as azide components in Cu-catalyzed clickreaction with alkynes. This method allows for efficient synthesis of a wide variety of N-heterocyclic derivatives of 1,2,3-triazoles.

A highly efficient copper(I)-catalyzed azideâalkyne cycloaddition (CuAAC) of 6-substituted tetrazolo[1,5-a]pyridines was developed for the preparation of 1-(pyridin-2-yl)-1,2,3-triazoles by simply using copper(I) acetate as a catalyst. The in situ formed HOAc played important dual roles and an activation of 2-azidopyridineâcopper(I) complex was observed.
