The N-glycosyl-2, 4-dinitrobenzenesulfonamides were accessed via benzoyl-protected β- glycosyl azides. The azides were reduced with Adams' catalyst to the corresponding amines. The glycosylamines were sulfonated with 2, 4-dinitrobenzenesulfonyl chloride to form N- glycosyl-2, 4-dinitrobenzenesulfonamides in moderate yields. β-Glycosyl amides were then prepared in 67% to 81% yields by treatment of the sulfonamides with thioacetic acid and ...
