Regioselective synthesis and biological evaluation of spiro-sulfamidate glycosides from exo-glycals

We report the synthesis of spiro-sulfamidate glycosides from exo-glycals. This route is regioselective and furnishes an original class of spiro-hydantoin glycoside analogues. A biological evaluation of this family on a range of glycosidases shows that these compounds are weak but very selective inhibitors of α-glucosidase and amyloglucosidase.
