摘要: 本文采用α-氨基膦酸酯与N-氯乙酰基氨基酸酯进行反应,合成了通式为(PhO)2POCHRNHCH2CONHCHR1COOR2的一系列新型含磷二肽,通过1HNMR、IR、MS和元素分析证明了其结构。初步生物活性测定表明其中有些化合物具有较高的选择性除草活性。

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
