TRIFLUOROMETHYL FURANOSIDE DERIVATIVE AND PRODUCTION THEREOF

摘要

NEW MATERIAL:A 2,3-dideoxy-8-trifluoromethyl pentofuranoside derivative of formula I (R is residue of nucleic acid base or nucleic acid base analogue). EXAMPLE:1-(2,3-dideoxy-3-trifluoromethyl pentofuranosyl)urasil. USE:Antineoplastic agents and antiviral agents. PREPARATION:A 1-substituted-2,3-dideoxy-3-trifluoromethyl pentofuranoside derivative of formula II (R<1> and R<2> are each protective group of H or OH) is converted into a nucleoside using a residue of a nucleic acid base.
