Copper(I)-Catalyzed Synthesis of Novel 4-(Trifluoromethyl)-[1,2,3]triazolo[1,5-a]quinoxalines via Cascade Reactions of N-(o-Haloaryl)alkynylimine with Sodium Azide

Novel tricyclic 4-(trifluoromethyl)-[1,2,3]triazolo[1,5-a]quinoxalines were readily prepared from N-(o-haloaryl)alkynylimines and sodium azide via copper(I)-catalyzed tandem reactions. This synthetic strategy provides an efficient way to access a library of novel heterocyclic compounds that are of interest in drug discovery.
