A method for synthesizing monofluoromethyl- and difluoromethyluracil nucleosides from the corresponding thymine nucleosides is developed. These compounds which contain a partially fluorinated methyl group at the C-5 position (a new class of nucleosides) are potential antiviral and/or anticancer agents. The major features of the preparative route involve bromination of suitably protected thymine nucleosides followed by fluoride treatment.
