The strategy involves a copper-catalyzed multicomponent reaction of sugar-derived alkynes with tosyl azide and salicylaldehyde to give a diverse array of glycosyl iminocoumarins in good yields. These compounds can serve as appropriate precursors for the synthesis of the corresponding coumarin 3-C-glycosides.
