Phenylthio group at the C-6 position of uridine serves as the protecting group during lithiation at the C-5 position with lithium 2,2,6,6-tetramethylpiperidine.Reactions of the resulting C-5 lithiated species with various types of electrophiles furnish 5-substituted 6-phenylthiouridine derivatives.The phenylthio group in these products can be removed by a new type of desulfurizative stannylation with tributyltin hydride followed by protonolysis.The whole sequence constitutes a new route to 5-substituted uridines.Application of this method to 2'-deoxyuridine is also described.

Phenylthio group in the C-6 or C- position of uracil moiety can be removed by radical mediated stannylation with tributyltin hydride followed by protonolysis, providing a new route to 5-substituted uridines.
