In an attempt to search for novel compounds with agricultural bioactivity,a series of new polysubstituted pyridine derivatives,α-[2-methyl-5-cyano4-(furan-2-yl)-3-ethoxycarboxyl-pyridine-6-thio]acetamide 4a, 2-methyl-5-cyano-4-(furan-2-yl)-3-acetyl pyridine-6-thioethers 5 and 6a were designed and synthesized by a three-step or one-step synthetic route.The structures of all the compounds prepared were confirmed by elemental analysis and 1H NMR.The preliminary bioassay results indicate that compound 4a possesses certain fungicidal and herbicidal activities.
