favorable herbicidal activity, a range of phenylpyridine moiety-containing pyrazole derivatives were designed, synthesized, and identified via NMR and HRMS. Their herbicidal activities against six species of weeds were evaluated in a greenhouse via both pre- and post-emergence treatments at 150 g a.i./hm2. The bioassay revealed that a few compounds exhibited moderate herbicidal activities against Digitaria
为了发现具有良好除草活性的新化合物,设计、合成并通过 NMR 和 HRMS 鉴定了一系列含有苯基吡啶部分的吡唑衍生物。在温室中通过芽前和芽后处理以 150 g ai/hm 2评估了它们对六种杂草的除草活性。生物测定表明,一些化合物在出苗后处理中表现出对血红木、Abutilon theophrasti和狗尾草的中度除草活性。例如,化合物6a和6c对狗尾草表现出 50% 的抑制活性, 略优于 pyroxasulfone。因此,化合物6a和6c可作为发现芽后除草剂的新的可能的先导化合物。
