pyrazole-4-carboxylic oxime ester derivatives were synthesized from benzaldehyde oxime and 3-(trifluoromethyl)-1-methyl-1H-pyrazole-4-carbonyl chloride conveniently. These pyrazole-4-carboxylic oxime ester structures were confirmed by 1H NMR and HRMS. The compound 5f was further confirmed by X-ray diffraction. They crystallized in the monoclinic system, space group C2/c, Z = 8. The fungicidal activity results indicated
以苯甲醛肟和3-(三氟甲基)-1-甲基-1H-吡唑-4-碳酰氯为原料合成了15种新型吡唑-4-羧肟酯衍生物。这些吡唑-4-羧酸肟酯结构通过1 H NMR 和HRMS 证实。通过X射线衍射进一步证实了化合物5f 。它们在单斜晶系中结晶,空间群C2/c,Z = 8。杀菌活性结果表明,其中一些化合物对核盘菌、灰霉病菌、茄病菌、稻瘟病菌和青霉病菌具有良好的活性。在 50 ppm。此外,通过分子对接模拟研究了构效关系。
