摘要：
Novel 2-(8-azabicyclo[3.2.1]octan-3-yl)-3-imino-2,3-dihydro-1H-isoindol-1-ones derived from 5-HT3 receptor antagonists hexahydroazepinylbenzamides were designed and synthesized through isocyanide insertion reaction. All target compounds were evaluated against pinewood nematodes B. xylophilus and root-knot nematodes M. incognita. Good lethal rate (75%) for 3-(tert-butylimino)-5-chloro-2-(8-methyl-8-azabicyclo[3.2.1]octan-3-yl)-2,3-dihydro-1H-isoindol-1-one and serious nervous curl effect against pinewood nematodes B. xylophilus for 3-(tert-butylimino)-2-(8-methyl-8-azabicyclo[3.2.1]octan-3-yl)-2,3-dihydro-1H-isoindol-1-one were observed at 10 mg/l. The inhibition activities of 3-[(4-methoxyphenyl)imino]-2-(8-methyl-8-azabicyclo[3.2.1]octan-3-yl)-2,3-dihydro-1H-isoindol-1-one against root-knot nematodes M. incognita were 84% at 160 mg/l and 60% at 20 mg/l for in vitro test and test tube test, respectively.
