Nucleophilic addition of dimethyl phosphite to acylamino ketones prepared conveniently by the Dakin-West reaction involving reaction of the corresponding α-amino acids and acid anhydrides, followed by subsequent hydrolysis affords 1-alkyl(aryl)-2-amino-1-hydroxyalkylphosphonic acids in satisfactory yield.
