Abstract: It was reported in literature that phosphonodipeptides had significant biological activities.In order to look for new herbicides, a series of novel phosphonodipeptides have been prepared by the reaction of (PhO)2P(O)CH2NH2 or (EtO)2P(O)CH2NH2 with ClCH2CONHCHR COOR'and ClCH2CONHCHRP(O)(OPh)2 separately in the presence of triethylamine in benzene.The structures of all the compounds prepared were proved by 1H NMR, IR and MS.Their spectroscopic spectra and biological activities were discussed.It was found that some of them showed good herbicidal activity.

Key words: a-aminoalkyl phosphonate ester, Phosphonodipeptide, Herbicidal activity
