results of a preliminary bioassay (in vitro) indicated that some of the title compounds 3 possessed moderate to good herbicidal activities against dicotyledonous plants (Brassica campestris L) at the concentration of 100 mg/L, and most of these compounds exhibited higher herbicidal activities against dicotyledonous plants (Brassica campestris L) than monocotyledonous plants (Echinochloa crus-galli).

在二环己基碳二亚胺 (DCC) 存在下,通过 O,O-二乙基 α-氨基取代苄基膦酸酯 1 和 4-甲基-[1,2,3] 噻二唑-5-羧酸 2 缩合合成目标化合物 3试剂。它们的结构通过光谱数据(IR、1H NMR、31P NMR、MS)和元素分析得到证实。初步生物测定(体外)结果表明,部分标题化合物3在浓度为100 mg/L时对双子叶植物(Brassica campestris L)具有中至良好的除草活性,其中大部分化合物表现出较高的除草活性对双子叶植物 (Brassica campestris L) 比单子叶植物 (Echinochloa crus-galli) 更有效。补充材料可用于本文。去出版商'
