Abstract: According to bioisosteric relationship and the mode of action between Neonicotinoid compounds and acetylcholin esterase, two series of Neonicotinoid compounds 2-substituted-3-(2-chloro-5-pyridinemethylene)-4-cyanoimino-1,3-thiazolidine(8a—8c) and 5-arylidene-2-aryl-3-(2-chloro-5-pyridinemethylene)-4-thiazolidinones(5a—5e) were designed and synthesized from 4-thiazolidinones(4). Intermediates 4 were synthesized by the condensation of amine, aldehyde and mercapto acetic acid. Their structures were character-ized via elemental analysis, 1H NMR spectra. The preliminary bioassay results show that some title compounds exhibited certain fungicidal activities, promoting cucumber cotyledon root-formation activities and compound 8b showed favourable anti-HIV PR.
