A new type of herbicides based on imidazolinones has been introduced into agriculture under commercial names of Arsenal, Pursuit, Scepter, Assert etc. by American Cyanamid Company since 1983. These compounds destroy diocotyledonous weeds and are almost nontoxic for mammals and fish (LD50 rat - 500 mg/kg, LD50 trout - 300 mg/kg) and nonmutagenic according to the AMES test. The aim of the present work is to synthesize substituted 2-benzoylaminocarboxamides as starting materials for preparation of imidazolinones and potential biologically active substances (Formulae I - III).
一种基于咪唑啉酮的新型除草剂自1983年起由美国赛诺美公司推出,商业名称为Arsenal、Pursuit、Scepter、Assert等。这些化合物能够消灭双子叶杂草,对哺乳动物和鱼类几乎无毒(LD50 大鼠 - 500 毫克/千克,LD50 鳟鱼 - 300 毫克/千克),根据AMES试验结果,这些化合物不具有致突变性。本研究的目的是合成取代的2-苯甲酰氨基羧酰胺,作为制备咪唑啉酮和潜在生物活性物质的起始原料(式 I - III)。
