Domino reactions between NH-based secondary enaminones and tosyl azide enable the synthesis of various N-substituted 1,2,3-triazoles via a key Regitz diazo-transfer process by employing t-BuONa as the base promoter. The reactions proceed efficiently at room temperature with good substrate tolerance.
