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.
