Six N4-substituted semicarbazides, which were synthesized using substituted amines as starting material, were reacted with five 3-(1-hydroxyethylidene)pyrrolidine-2,4-diones to give twenty two novel (Z,E)-1-[1-(2,4-dioxo-pyrrolidine-3-ylidene)ethyl]-4-alkylsemicarbazide derivatives. The structures of the target compounds were confirmed by 1H NMR, MS, IR techniques and elemental analysis. The preliminary bioassay results indicated that these compounds exhibited certain inhibitive activities against the root of Brassica napus and the stalk of Echinochloa crusgalli.

Key words: semicarbazone, pyrrolidine, synthesis, herbicidal activity
