Synthesis of 5'-methylene-phosphonate furanonucleoside prodrugs: application to D-2'-deoxy-2'-α-fluoro-2'-β-C-methyl nucleosides.

ABSTRACT: A new and facile synthetic pathway to metabolically stable 5'-methylene-bis(pivaloyloxymethyl)(POM)phosphonate furanonucleoside prodrugs is reported. The key step involves a Horner-Wadsworth-Emmons reaction of a tetra(pivaloyloxymethyl) bisphosphonate salt with appropriately protected 5'-aldehydic nucleosides. This efficient approach was applied for the synthesis HCV related 2'-deoxy-2'-α-fluoro-2'-β-C-methyl nucleosides.
