NEW MATERIAL:Phosphoric acid esters of 3'-deoxy-3'-fluoronucleoside derivatives expressed by the formula (B is residue of nucleic acid bases). EXAMPLE:3'-Deoxy-3'-fluoroadenosine-5'-monophosphate. USE:A medicine, such as antitumor and antiviral agents. PREPARATION:For example, triazole is suspended in methylene chloride and o-chlorophenyl phosphorodichloridate which is a phosphorylating agent is added to the resultant suspension while cooling with ice and stirred. A solution of the compounds expressed by the formula, such as N<6>,2'-O-dibenzoyl-3'-deoxy-3'- fluoroadenosine, in pyridine-methylene chloride is added thereto and reacted to carry out phosphorylation of the compounds expressed by the formula.
