Efficient methods for the synthesis of α-aminophosphonate fluoroalkyl esters

Two novel synthetic methods for the preparation of bis(trifluoroethyl) esters of α-aminophosphonic acids are presented. Preliminary results on the application of the compounds synthesized as inhibitors of serine proteases are also reported. Structures originating from α-aminoalkylphosphonate diaryl esters represent a novel class of serine protease inactivators.
