Novel 1-phenyl-piperazine-2,6-diones were prepared by a new facile synthetic routeusing methyl N-substituted iminomonoacetate as starting material. The structures of thesecompounds were established by 1H-NMR, 13C-NMR and GC/MS. 2-(4-Chloro-5-cyclo-pentyl-oxy-2-fluorophenyl)-tetrahydro-2H-pyrido-[1,2-a]-pyrazine-1,3-(4H,6H)-dione displayed thegreatest herbicidal activity.
新型1-苯基-哌嗪-2,6-二酮通过一种新的简便合成路线,使用N-取代的甲基单乙酸亚胺作为起始材料制备而成。这些化合物的结构通过1H-NMR、13C-NMR和气相色谱/质谱(GC/MS)确立。2-(4-氯-5-环戊基-O-2-氟苯基)-四氢-2H-吡啶-[1,2-a]-吡唑-1,3-(4H,6H)-二酮表现出最强的除草活性。
