摘要:

通过组合不同除草作用机制的活性基团,采用芳氧乙酸为酸组分的Ugi四组分反应合成了一系列芳氧乙酰基和间三氟甲基苯基片段的双酰胺化合物3a~3v,采用IR、1H NMR、EI-MS和元素分析等技术手段对其结构进行了表征。 温室盆栽测试结果表明,部分目标化合物对油菜、反枝苋、稗草和马唐表现出中等至良好的除草活性,如化合物3r在温室盆栽时,在1.5 kg/ha剂量下,在苗前处理时对反枝苋和马唐显示出100%的抑制活性;在苗后处理时对马唐显示出100%的抑制活性。 初步探讨了目标化合物的构效关系。

Abstract:

Based on the combination of different active groups with different herbicidal modes of action, a series of diamide compounds 3a~3v containing of 2-(aryloxy)acetyl and meta-trifluoromethylphenyl moieties were designed and synthesized via the four-component Ugi reaction. Their structures were characterized by IR, 1H NMR, EI-MS, and elemental analyses. The glass house bioassay(in vivo) shows that some of compounds 3 exhibit moderate to good herbicidal activities against B.campestris, A.retroflexus, E.crusgalli, and D.sanguinalis at a dose of 1.5 kg/ha. For example, compound 3r displays 100% inhibition aganist both of A.retroflexus and D.sanguinalis in the pre-emergence treatment, it also exhibits 100% inhibition aganist D.sanguinalis in the post-emergence treatment. In addition, the preliminary structure-activity relationships are also discussed.
