The reaction of lithium salts of dialkyl methylphosphonates with suitably protected amino acid methyl esters at low temperature, followed by removal of protecting groups in the presence of trimethylsilyl bromide provides an efficient method for the synthesis of the titled compounds.

esters 26–31. The protective groups of 26–28 have been removed by mineral and selective enzyme-catalyzed hydrolysis to give 2–4, while the protective groups of 29-31 removed by treatment with phosphorus pentachloride to 32–34, followed by enzyme and mineral hydrolysis to 5–7. Upon mineral hydrolysis of 14–17, 26, and 29, the aminoketophosphinic acid 35 and the aminoketophosphonic acid 36 have been isolated
