Glycosyl phenyl sulfone obtained in 4 steps from isosaccharino-lactone was convened into a 2'-C-acetoxymethylfuranoid glycal with SmI2-HMPA. Coupling of this glycal with silylated thymine or cytidine in the presence of Pd(0) led after deprotection, to the 2'-deoxy-2'-methylidene-5-methyluridine and to tire 2'-deoxy-2'-methylidene cytosine, respectively.
