Abstract: Three chiral phosphonoacetamides were prepared by an alternative method . For this purpose, 2-(diethoxyphosphoryl)acetic acid was prepared from ethyl 2-bromoacetate by treatment of P(OEt) 3 followed by saponification of the ester with K 2CO 3. BOP activated amidation of the 2-(diethoxyphosphoryl)acetic acid with (S)-amino acids gave the corresponding phosphonoaceteamides. Growth inhibition of two phosphonoacetamides on Paramecium sp. were studied.
