A general synthetic approach to 2,3-unsaturated glycosides connecting with
nucleosides involving Ferrier rearrangements of glycals is discussed. The n
ew compounds were identified by NMR and MS (HRFAB(+)). The hydroxylation of
the resulting 2,3-unsaturated glycosides was completed using OsO4 to give
5'-O-glycosylnucleosides in good yield. (C) 1999 Elsevier Science Ltd. All
