Acylamino carboxylic acids were degradated by the Hunsdiecker-reaction; the bromo-derivatives were reacted with NaPO(OC2H5)2. Aminophosphonic acids were obtained by acidic hydrolysis, and half-blocked derivatives by the selective removal of masking substituents. Two phosphonopeptides [e.g. Alafosfalin (4i)] were also prepared by this route.

1-(N-Trifluoroacetylamino)alkanephosphonate 0,0-diethyl esters 2 C, obtained from parent 1-aminoalkanephosphonic acids 1, have been selectively deprotected on the amino function affording 0,0-diethyl 1-aminoalkanephosphonates 3. Protonation constants of all amino esters 3 synthesized have been determined by potentiometric titration.
