Abstract

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