title: Synthesis of 3'-trifluoromethyl nucleosides as potential antiviral agents.
abstract: 1,2-Di-O-acetyl-3-deoxy-3-trifluoromethyl-5-O-benzoyl-beta-D-ribofuranos e was synthesized from the precursor keto sugar by the use of Ruppert's reagent (CF3SiMe3) as the source of a nucleophilic trifluoromethyl group. Coupling of this trifluoromethyl sugar with nucleobases and elaboration gave novel deoxy and dideoxynucleosides. A single crystal X-ray analysis confirmed the structure and stereochemistry. The deoxynucleosides were converted through an elimination reaction to their dideoxydidehydro derivatives.
