摘要
Reactions of glycals with the combination iodonium di-rym-collidine perchlorate (5) and benzenesulfonamide (6) afforded, stereoselectivity, 2-β-iodo-1-α-sulfonamidohexoses. This process was demonstrated with D-glucal, D-galactal, and D-allal. Treatment of these products with strong base apparently generated a C1-C2 sulfonylaziridine. A 2-α-sulfonamide-1-β-linked disaccharide was produced when this reaction was carried out with excess base in the presence of a glycosyl acceptor. © 1990, American Chemical Society.
