Abstract To explore a new skeleton with nematicidal activity, a series of novel azabicyclo derivatives containing a thiazole moiety were designed, synthesized and evaluated for their nematicidal activities. The bioassay results against pine-wood nematodes (Bursaphelenchus xylophilus) showed that most of the title compounds displayed nematicidal activity at a concentration of 40 mg/L. Especially, the title compounds2-((8-methyl-8-azabicyclo[3.2.1]octan-3-yl)oxy)-4-(4-chlorophenyl)thiazole (7e), 2-((8-methyl-8-azabicyclo[3.2.1]octan-3-yl)thio)-4-phenylthiazole (10a) and 2-((8-methyl-8-azabicyclo [3.2.1]octan-3-yl)thio)-4-(4-chlorophenyl)thiazole (10e) exhibited more than 90% mortality against Bursaphelenchus xylophilus.

含有噻唑部分的新型氮杂双环衍生物的合成及其对松材线虫的生物活性

摘要为了探索具有杀线虫活性的新骨架，设计、合成了一系列含有噻唑部分的新型氮杂双环衍生物并评价了它们的杀线虫活性。针对松材线虫 (Bursaphelenchus xylophilus) 的生物测定结果表明，大多数标题化合物在 40 mg/L 的浓度下显示出杀线虫活性。特别是，标题化合物 2-((8-methyl-8-azabicyclo[3.2.1]octan-3-yl)oxy)-4-(4-chlorophenyl)thiazole (7e), 2-((8-methyl-8 -氮杂双环[3.2.1]辛基-3-基)硫基)-4-苯基噻唑(10a)和2-((8-甲基-8-氮杂双环[3.2.1]辛基-3-基)硫基)-4- (4-氯苯基)噻唑 (10e) 对松材线虫的死亡率超过 90%。图形概要
