Tunable Synthesis of 1,2,3‐Triazoles and Enamines through Deacylative Azide‐Alkene Cycloaddition

A tunable synthesis of 1,4,5‐trisubstituted 1,2,3‐triazoles and enamines through [3+2] cycloaddition of activated olefins and organic azides is reported. Triazoles were achieved from benzylidene diketones and organic azides by copper oxide nanoparticle catalysis while enamines were synthesized from benzylidene malonates and organic azides under solvent‐free and catalyst‐free condition.
