Abstract: In order to look for a new herbicide, a series of novel phosphonodipeptides have been prepared by the reaction of (PhO)2P(O)CHRNH2 with C1CH2CONHCHR'COOR2 in the presence of tri-ethylamine in benzene.The structures of all the compounds prepared were proved by 1H NMR, IRand MSand some of them by elementary analysis.The preliminary biological tests indicated that some of them showed a highly selective herbicidal activity.

Key words: α-Amino phosphonate ester, Phosphonodipeptide, Herbicidal activity
