A new method for the synthesis of 2′-O,5-dimethyluridine (5) has provided the title compound in a higher yield. Application of a one-pot ribosylation methodology resulted in an efficient, high yield synthesis of 5-methyluridine (ribothymine, 3b). An X-ray diffraction analysis of 5 disclosed the conformation of the sugar moiety of this nucleoside as anti, N(3′-endo), g+.
