S-Glycosides possessing silyl enol ether groups tethered via an ether linkage undergo highly selective cation-mediated cyclisation reactions to give C-glycosidic ketotetrahydropyran-containing bicyclo[4.4.0] systems. These may be converted into a variety of monocyclic C-glycosides and their derivatives using oxidative and reductive tether-cleaving reactions. (C) 1998 Elsevier Science Ltd. All rights reserved.
