A series of amide derivatives containing aromatic sulfide and sulfone groups synthesized in our previous work displayed excellent nematocidal activity at 200 μg/mL. In order to explore the effect of structural modification of the amide bridge on biological activity in a more delicate way, two series of novel target compounds were designed and synthesized by adopting amide group flipping and introducing N-sulfonyl substituted amide bonds. The bioassays indicated that the structural modification of the amide bridge had important effects on their nematocidal and fungicidal activities, which the introduction of the N-sulfonyl substituent on the amide group was favorable to improving the nematocidal activity in comparison with compounds I. The molecular docking revealed that directly attaching the carbonyl or sulfonyl groups in the amide bridge to the aromatic rings was advantageous to the nematocidal activity.
