were evaluated in vitro for their antifungal activity against Rhizoctorzia solani, Fusarium oxysporum, Botrytis cinerea Pers., sunflower sclerotinia rot, and rape sclerotinia rot by mycelia growth inhibition assay at 50 μg/mL. The antifungal evaluation of the novel hybrids showed that, among the tested compounds, 5a, 5b, 5c, and 9b showed good antifungal activity against sunflower sclerotinia rot.
铜催化叠氮化物和末端炔环加成反应,即“点击化学”,为制备l,4-二取代-l,2,3-三唑提供了一种新的、便捷的方法。在这项工作中,2-吡咯碳亚胺基Cu(II)配合物被建立为芳基硼酸和叠氮化钠(NaN₃)与末端炔烃在乙醇中在室温至50°下进行三组分1,3-偶极环加成反应的有效催化剂。合成了C,1,4-二取代的1,2,3-三唑。按照优化方案,设计并合成了两个系列的新型芳基-1,2,3-三唑-β-咔啉杂化物,并通过 1H NMR、13C NMR 和高分辨率质谱(HRMS)对化学结构进行了表征。 )。通过菌丝体生长抑制测定,在体外评估了所有目标化合物对立枯丝核菌、尖孢镰刀菌、灰葡萄孢、向日葵菌核病和油菜菌核病的抗真菌活性。对新型杂种的抗真菌评价表明,受试化合物中,5a、5b、5c和9b对向日葵菌核腐病表现出良好的抗真菌活性。具体而言,化合物9b对所有测试的真菌均表现出高广谱杀菌作用,抑制率分别为58
