Stereoselective synthesis of novel 2′-fluoro and 2′,4′-dimethyl carbocyclic pyrimidine C-nucleoside analogues using selective fluorination of an epoxide opening reaction is described. The key fluorinated intermediate 7 was prepared from the epoxide intermediate 5 via selective ring opening of the epoxide. Synthesis of isonucleosidic bases through the mesylate 7 and final deprotection provided the target

2-Methyl-2-cyclopentene-1-one was used as starting material in a novel route toward 2'-branched-carbocyclic nucleosides. Thin methodology was efficiently adapted to the Preparation of 4'-epi-carbocycles. A series of this new class of molecules was synthesized as potential antiviral compounds.
