NEW MATERIAL:Compounds expressed by formula I (B is residue of nucleic acid bases). EXAMPLE:9-(2,3-Dideoxy-3-fluoro-beta-D-xylofuranosyl)-6-dimethylaminom ethylenea minopurine. USE:An antitumor and antiviral agents. PREPARATION:For example, the hydroxyl group at the 2'-position of a fluoroadenosine expressed by formula II (B' is adenyl; R<1> is H; X is H) is reacted with a reactant, such as N,N'-thiocarbonyldiimidazole, and converted into a leaving group. A reducing agent, such as tributyltin hydride, is then reacted with the above-mentioned compound to remove the leaving group and carry out removal of the hydroxyl group at the 2'-position.
