AbstractCopper-catalyzed reactions of N-propargyl-N-(2-iodoaryl)amides with sodium azide have been developed, providing a novel and efficient method for the synthesis of [1,2,3]triazolo[1,5-a]quinoxaline compounds under mild conditions in moderate yields by tandem copper-catalyzed azide-alkyne cycloaddition and Ullmann-type coupling.

A concise one-pot three-component reaction of organic halides­, terminal acetylenes, and sodium azide provided an efficient route for the synthesis of 1,2,3-triazoles. A variety of 1,2,3-triazoles were prepared in good to excellent yields with green solvent glycerol. This procedure used CuI and diethylamine, which are two easily available reagents as the new catalytic system at room temperature.

A diversified synthesis of 2-(4-oxo[1,2,3]triazolo-[1,5-a]quin­oxalin-5(4H)-yl)acetamide derivatives is demonstrated. The protocol employs a Ugi four-component reaction for the assembling of N-(2-haloaryl)propynamide intermediates and followed by a copper-catalyzed tandem reaction of the synthetic N-(2-haloaryl)propynamides with sodium azide. Such a method provides rapid access to structurally varied and complex fused tricyclic scaffolds through readily available starting materials.
