Abstract

A simple and efficient metal-free methodology for the regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles has been developed by applying a novel inverse electron-demand-1,3-dipolar cycloaddition approach. The practical one-pot metal-free strategy can be accomplished with various alkylidene malononitriles and aromatic azides in the presence of base. (AU)
