    Project supported by the National Natural Science Foundation of China (No. 21372135), the Research Foundation of the Six People Peak of Jiangsu Province (No. 2013-SWYY-013) and the Science and Technology Innovation Foundation for the College Students of Jiangsu Province (No. 201610304047Z).

In order to find new cyanoacrylate lead compounds, a series of novel cyanoacrylates containing substituted pyridyl moiety were prepared by the method of active substructure combination. The structures of the target compounds were confirmed by 1H NMR, 13C NMR and elemental analyses. Preliminary bioassay data displayed that in postemergence treatment 2-cyano-3-methylthio-3-[4-(5-trifluoromethylpyridyl-2-amino)]benzylamino(2-methoxy)ethyl ester (7l) had 95% herbicidal activity against Brassica juncea at 1500 g/ha and 2-cyano-3-methylthio-3-[4-(5-trifluoromethylpyridyl-2-amino)]benzylamino-[2-(2,4-difluorophenoxy)]ethyl ester (7e), 7l and 2-cyano-3-methylthio-3-[4-(5-trifluoromethylpyridyl-2-amino)]benzylamino-(2-ethoxy)ethyl ester (7m) showed 80%, 80% and 100% herbicidal activity against Stellaria media, respectively. Additionally, 2-cyano-3-methylthio-3-[4-(5-trifluoromethylpyridyl-2-amino)]benzylamino[2-(2-fluorophenoxy)]ethyl ester (7b), 7l and 7m all exhibited 100% herbicidal activity against Chenopodium serotinum L. at 1500 g/ha.

Key words: pyridine, cyanoacrylate, synthesis, herbicidal activity
