with high activity against resistant pathogens, twelve (E)‐α‐(methoxyimino)benzeneacetate derivatives containing 1,2,4‐triazole Schiff base side chain 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l were designed and synthesized. Their structures were confirmed by IR, 1H‐NMR, EIMS, and elemental analyses. Bioassays indicated that most of the target compounds showed moderate to good fungicidal activities
要找到对抵抗病原体具有高活性的新球果伞素类似物,需要十二种(E)-α-(甲氧基亚氨基)苯乙酸衍生物,它们含有1,2,4-三唑希夫碱侧链3a,3b,3c,3d,3e,3f,3g,设计并合成了3h,3i,3j,3k,3l。通过IR,1 H-NMR,EIMS和元素分析确认了它们的结构。生物测定法表明,大多数目标化合物对中毒表现出中等至良好的杀菌活性。Physalospora piricola鼻子和黑链格孢菌。例如,化合物3d,3e和3f对Physalospora piricola Nose具有99.5%,100%和95.6%的抑制作用,而化合物3d,3f和3g在该温度下对solternaria solani的抑制作用分别为92%,91%和92%。浓度分别为50 mg / L。
