A novel process for the preparation of a fluorolactone derivative of the formula (I) and of its acylated derivative of formula (V) wherein R1 stands for a hydroxy protecting group is described. The acylated fluorolactones of formula (V), particularly the benzoyl derivative with R1 =benzyl are important precursors for the synthesis of prodrug compounds which have the potential to be potent inhibitors of the Hepatitis C Virus (HCV) NS5B polymerase.
