prepared a series of new substituted pyrazolyl benzoxazole derivative, which were synthesized from 4-fluorophenol, via a serial of reactions included chlorination, acylation, condensation, ring closure, methylation, nitration, and so on. All the structures are confirmed by 1H NMR, MS and element analysis. Preliminary bioassay shows that most substituted pyrazolyl benzoxazole derivatives exhibit high herbicidal
最近几年, 原卟啉原氧化酶(Protox)抑制剂除草剂发展很快,因为这种除草剂显示出高除草活性和低毒性。本文制备了一系列新的取代的吡唑基苯并恶唑衍生物,它们是由4-氟苯酚通过一系列反应包括氯化,酰化,缩合,闭环,甲基化,硝化等。所有结构均通过1 H NMR,MS和元素分析确认。初步的生物测定表明,大多数取代的吡唑基苯并恶唑衍生物对所测试的禾本科杂草和阔叶杂草表现出很高的除草活性。J.杂环化学。(2010)。
