Glycosylated N-sulfonylamidines: highly efficient copper-catalyzed multicomponent reaction with sugar alkynes, sulfonyl azides, and amines

Copper-catalyzed multicomponent reactions with sugar, alkynes, sulfonyl azides, and amines to produce glycosylated N-sulfonylamidines are described. The reaction is shown to be general in terms of different combinations of sugar alkyne, sulfonyl azide and amines.
