A method for the manufacture of compounds containing an α-oxy phosphorus group is disclosed. A P-O component having at least one P-O-P moiety, whereby at least one phosphorus has the +3 oxidation state, is added in specific proportions to a compound containing an α-oxy carboxylic acid group, followed by conducting the reaction and adding water subsequently. The compounds containing an α-oxy phosphorus group formed can then be recovered.

An improved synthesis of the antiviral drug adefovir is presented. Problems associated with current routes to adefovir include capricious yields and a reliance on problematic reagents and solvents, such as magnesium tert-butoxide and DMF, to achieve high conversions to the target. A systematic study within our laboratory led to the identification of an iodide reagent which affords higher yields than
