Reaction between suitably protected furanoid glycals 1b-4b, readily obtained from furanoid 1,2-diols (1a-4a), and different silylated pyrimidine bases, gave the corresponding 3',5'- and 3',5',6'-O-protected 2'-deoxy-2'-iodo-beta-D-xylo-pentofuranosyl 5-10 and beta-D-gluco-hexofuranosyl 11 nucleosides, respectively. Compound 5 has been transformed into its 2'-deoxy 12 and 2',3'-anhydro 14 derivatives. The high stereoselectivity of the reaction is discussed. (C) 1997 Elsevier Science Ltd.
