Six previously unreported peptides containing diethyl DL-1-aminobenzylphosphonate terminal unit were prepared. These are: Diethyl phthalyl-glycyl-gly-DL-1-aminobenzylphosphonate, diethyl gly-gly-DL-aminobenzylphosphonate, diethyl phthalyl-gly-gly-gly-DL-1-aminobenzylphosphonate , diethyl phthalyl-gly-gly-gly-gly-DL-1-aminobenzylphosphonate, diethyl phthalyl-DL-1-phenylalanyl-DL-1-aminobenzylphosphonate, diethyl phthalyl-gly-DL-phenylalanyl-DL-1-aminobenzylphosphonate. All the compounds were obtained as white crystalline powder and characterized by means of elemental analysis, IR spectroscopy, NMR spectroscopy, and ninhydrin test.
