were synthesized, and their insecticidal activity against Nilaparvata lugens and Aphis craccivora was evaluated. The compound structure was identified by NMR, HRMS, and single-crystal diffraction. The bioassay results indicated that compound 4-1 (R1 is chloropyridine, R2 is H), 4-2 (R1 is chlorothiazole, R2 is H) and 4-19 (R1 is benzyl, R2 is isopropyl) had the best activity against Nilaparvata lugens
合成了一系列含有三氟乙酰基的化合物,并对其对褐飞虱和Aphis craccivora的杀虫活性进行了评价。通过NMR、HRMS和单晶衍射鉴定了化合物的结构。生物测定结果表明化合物4-1(R 1为氯吡啶,R 2为H)、4-2(R 1为氯噻唑,R 2为H)和4-19(R 1为苄基,R 2为异丙基)在 100 mg/L 浓度下对褐飞虱的活性最高(93.5%、94.1% 和 95.5%)。R 1或R 2不同取代基的影响通过构效关系研究活性。讨论了化合物 4-1 和 4-2 的分子对接。 图形摘要
