A new one-pot metal-free preparation of [1,2,3]triazolo[1,5- a]quinoxalines by a Ugi-3CR/alkyne-azide cycloaddition sequence has been developed. The reaction of 2-azidobenzenamines, propiolic aldehydes and isocyanides produced [1,2,3]triazolo[1,5- a]quinoxalines in 55%~85% yields via sequential Ugi-3CR/alkyne-azide cycloaddition reaction in the presence of H3PO4 and heating in toluene respectively.

Key words: one-pot, metal-free, [1,2,3]triazolo[1,5-a]quinoxaline, Ugi-3CR, alkyne-azide cycloaddition
