3′-Deoxy-3′-C-trifluoromethyl Nucleosides: Synthesis and Antiviral Evaluation

Abstract

2′,3′-Dideoxy-3′-C-trifluoromethylthymidine 9a and -uridine 9b and 3′-C-trifluoromethyl-d4T 11 were prepared in a few steps from 3′-deoxy-3′-C-trifluoromethyl-D-ribose, which synthesis was recently reported. The biological assessment of these nucleoside analogues did not reveal interesting antiviral properties against HIV-1, HSV-1, CMV, Vaccine, and Cox B4.
