基于具有潜在杀线虫活性的托烷衍生物结构,通过1,3-偶极环加成反应,设计合成了19个未见报道的8-氮杂双环[3.2.1]辛烷-3-异噁唑肟类衍生物,通过1H NMR,13C NMR和高分辨质谱对目标化合物的结构进行表征.初步的生物活性测试表明:在浓度25mg/L下,目标化合物对南方根结线虫表现出良好的抑制活性,活性最好的化合物8-甲基-8-氮杂双环[3.2.1]辛烷-3-酮-O-((3-(4-硝基苯基)-4,5-二氢异噁唑-5-基)甲基)肟(9e)在1mg/L浓度下对根结线虫的抑制率达55.6%.

Based on the potential nematicidal activities of tropane derivatives structure, 19 unreported 8-azabicyclo[3.2.1]- octane-3-isoxazole oxime derivatives were designed and synthesized by 1,3-dipolar cycloaddition reaction. Their structures were confirmed by 1H NMR, 13C NMR and HRMS techniques. Preliminary bioassay results showed that targeted compounds exhibited good nematicidal activities against Meloidogyne incognita at concentration of 25 mg/L, and 8-methyl-8-azabicyclo- [3.2.1]octan-3-one-O-((3-(4-nitrophenyl)-4,5-dihydroisoxazol-5-yl)methyl)oxime (9e) showed the best nematicidal activities with 55.6% at concentration of 1 mg/L.
