1,3-Dipolar cycloaddition of pyridynes and organic azides was investigated. Thus, 3,4-pyridynes and 2,3-pyridynes were reacted with various organic azides under mild conditions to afford the corresponding [1,2,3]triazolo[4,5-c]pyridines and [1,2,3]triazolo[4,5-b]pyridines, respectively. In the case of the reaction of 3,4-pyridyne, it was also found that a substituent on the pyridine ring affected the regioselectivity of the cycloaddition.
