Design and Synthesis of Benzoylphenylureas with Fluorinated Substituents on the Aniline Ring as Insect Growth Regulators
摘要:
Enormous numbers of synthetic fluorine-containing compounds have been widely used in a variety of fields, especially in drug and pesticide design. To find novel insect growth regulators, a series of benzoylphenylureas with fluorinated substituents were designed and synthesized. The results of larvicidal activities of those novel fluoro-substituted benzoylphenylureas against oriental armyworm and mosquito revealed that most compounds exhibited excellent activities. It is worth mentioning that compounds 3 and 6 exhibited higher activities against oriental armyworm and mosquito than commercial Hexaflumuron. It can be further seen that the insecticidal activities would increase significantly by introducing fluorinated substituents into the structure of the designed benzoylphenylureas.

Introduction: After using insecticides over many years, the resistance and environmental issues have become great challenges to crop protection. Modern agriculture calls for new insecticidal candidates. Phthalic diamideinsecticide containing adjacent two amide group were favored for its new mode of action. Most chemical optimizations of phthalic diamideinsecticide focused on amide groups. Modifications
简介:在使用杀虫剂多年后,耐药性和环境问题已成为保护作物的巨大挑战。现代农业要求有新的杀虫候选物。含有相邻两个酰胺基的邻苯二甲酸二酰胺杀虫剂因其新的作用方式而受到青睐。邻苯二甲酸二酰胺类杀虫剂的大多数化学优化都集中在酰胺基上。苯基部分的修饰包括较少的取代基类型。 目的:本文的目的是通过用氧二苯和二苯胺代替苯基部分来改变两种酰胺的方向和距离,从而研究杀虫活性的变化。 结果:以Cu / CuI催化的Ullmann偶联和磺酰基-O-丙烯酸混合酸酐为反应中间体,合成了目标化合物。评价了所有目标化合物的抗粘虫(Mythimna sepatara)。两种含有多氟烷氧基取代基的合成化合物在500 mg L -1下的死亡率为100%。基于DFT的势能表面扫描表明,三种构象的杀虫化合物的相对能非常相似。 结论:我们设计,合成和表征了十七种新颖的杀虫化合物。发现其中两个具有杀虫作用。初步的结构活性关系表明,苯

substructure were designed and synthesized. Their insecticidalactivities against armyworms (Mythimna sepatara) and aphis (Aphis craccivora) were screened. The compounds with 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl substituent were found to be insecticidal to armyworms with the similar symptoms to poisoning by flubendiamide. In this research, we presented a novel type of diamide insecticide as a lead

2‐tetrafluoroethoxy)phenylcontaining 4‐methyl‐1,2,3‐thiadiazole derivatives were designed and synthesized viaUgireaction. Their structures were confirmed by IR, 1H NMR, 13C NMR and high‐resolution mass spectroscopy. The preliminary bioassay results indicated that some title compounds had good fungicide activity at 50 µg/mL; most of the compounds presented a certain degree of direct inhibition activity, good inactivation
