benzothiophene-substituted oxime ether strobilurins, which employed a benzothiophene group to stabilise the E-styryl group in Enoxastrobin (an unsaturated oxime strobilurin fungicide developed by Shenyang Research Institute of Chemical Industry, China) were designed and synthesised. The biological assay indicated that most compounds exhibited good or excellent fungicidal activities, especially against Colletotrichum
设计并合成了二十一种新型的苯并噻吩取代的肟醚Strobilururins,它利用苯并噻吩基团稳定了Enostrobin(由中国沉阳化工研究院开发的一种不饱和肟Strobilurin杀菌剂)中的E-苯乙烯基。生物学测定表明,大多数化合物表现出良好或优异的杀真菌活性,尤其是对军需炭疽病和高粱普希氏菌的杀灭作用。此外,3-甲氧基丙烯酸甲酯肟醚和N-甲氧基氨基甲酸酯甲酯对Erysiphe graminis,Colletotrichum lagenarium和Puccinia sorghi Schw。在测试浓度下。值得注意的是,(E,E)-甲基3-甲氧基-2-(2-((((((6-chloro-1-(1 H -benzo [ b ] thien-2-yl)乙叉基)氨基)氧基)甲基)与依诺那酯相比,苯基丙酸酯(5E)在浓度为0.39 mg / L时对几乎所有测试真菌的体内杀真菌活性更高。
