The synthesis of 1,3,4‐thiadiazole skeleton compounds exhibiting high fungicidal activities has been demonstrated. Thirteen novel 1,3,4‐thiadiazolyl‐pyrazolines compounds containing ferrocene were designed and synthesized from the ferrocenylchalcones intermediates 3a–3m and the 2‐hydrazino‐5‐phenyl‐1,3,4‐thiadiazole intermediate 8. All compounds were characterized by 1H NMR, 13C NMR, FT‐IR spectra
已证明具有高杀真菌活性的1,3,4-噻二唑骨架化合物的合成。从二茂铁基查耳酮中间体3a - 3m和2-肼基-5-苯基-1,3,4-噻二唑中间体8设计并合成了13种新型的含二茂铁的1,3,4-噻二唑基-吡唑啉化合物。所有化合物的特征均通过1 H NMR,13 C NMR,FT-IR光谱和HR-MS以及一种新化合物N-(4-苯基-1,3,4-噻二唑-2-基)-3-二茂铁基-5-苯基吡唑啉9a通过X射线衍射分析进一步确定。生物学活性测定的初步结果表明,所有标题化合物对茄腐霉菌,桑赤霉和烟赤霉均表现出明显的杀真菌活性。此外,与对照药物吡菌胺酯相比,化合物9e和9h显示出对三种真菌种类更高的杀真菌活性。
