Abstract: Unequivocal synthesis of 3'-C-methyl-2'-deoxyuridine has been carried out. The proposed method consists in the preparation of 3',5'-di-O-blocked 3'-C-methyluridines followed by the radical reduction of their phenoxythiocarbonyl derivatives and deblocking. Tertiary 3'-hydroxyl of 3'-C-methyluridine is protected with either benzyl or tet-rahydropyranyl group, whereas benzoyl group is invariably used to block primary 5'-hydroxyl group.
