A synthesis of 5-fluoro-2'-ideoxycytidine, of oligonucleotides containing 5-fluoro-2'-deoxycytidine and of certain novel 4-alkoxy-5-fluoro-2'-deoxyuridines is disclosed. These 4-alkoxy compounds are useful intermediates for the preparation of other 4-substituted, 5-fluoro pyrimidine deoxynucleosides, and spontaneously hydrolyze in target cells to form FdU and derivatives thereof.
