Abstract	Six previously unreported N-acylated-DL-1-amino alkyl phosphonic acids were prepared; N-Acetyl-DL-1-amino-3-methyl butyl ,phosphonic acid, N-Benzoyl-DL-1-amino-2-methyl propyl phosphonic acid , N-Benzoyl-DL-1-amino-3-methyl butyl phosphonic acid, N-Benzoyl-DL-1-amino-2-methyl butyl phosphonic acid, N-Acetyl-DL-1-amino-2-methyl propyl phosphonic acid, N-Acetyl-DL-1-amino-2-methyl butyl phosphonic acid. The first four compounds were characterized, and the last two compounds were obtained in the scrude oil state. The above three DL-1-amino alkyl phosphonic acids were synthesized from iso-valeric acid, iso-caproic acid, and β-methyl valeric acid using Hell-Volhard-Zelinsky reaction, the condensation reaction with triethyl-phosphite and the modified Curtius Reaction. Iso-caproic acid and β-methyl valeric acid were prepared by the conventional methods.
