title glycals, prepared from S-glycoside dioxides using the Meyers' variant of the Ramberg-Bäcklund rearrangement are described. These include a formal total synthesis of a novel β-glycosidase inhibitor, and an efficient route to spirocyclic glucose derivatives. In addition, silyl methodology has been developed which allows unprotected exo-glycals to be synthesised.
