Design and synthesis of 1,2dihydroquinoline/chromene fused sugar triazole frameworks by copper catalyzed one pot, click and intramolecular arylation reactions

Expedient copper-catalyzed one-pot click and intramolecular arylation reactions have been developed for the synthesis of 1,2-dihydroquinoline/chromene-fused triazoles with varying sugar functionalities. It has been observed that the additive TMEDA greatly facilitates this copper-catalyzed cyclization. This reaction involves two mechanistically distinct reactions
