Abstract
The proposed short synthesis involves two key steps: Oxidation of the isopropylidene derivative of the 3-fluoronucleoside possessing a free hydroxyl group in 2-position and acetylation of deprotected 3-fluoro-2-ketonucleoside which, after a β-elimination reaction, gives the desired unsaturated ketonucleoside 5.
