中文摘要：
设计并合成了9个N（7-氟-3-氧-3，4-二氢-2H苯并[b][1，4]噁嗪-6-基-）-N＇，N＇-二取代脲类化合物，其化学结构经IR、^1HNMR、LCVMS确证。初步生物活性测定结果表明，部分化合物具有-定的除草活性，当茎叶处理使用剂量为75ga．i/hm^2时，化合物4e和4h对双子叶杂草刺苋的抑制率达70％以上。
英文摘要：
Urea compounds are one of the hot topic in the herbicide research, Nine N-（7-fluoro-2,4-disubstituted-3- oxo-3,4-dihydro-2H-benzo [b] [ 1,4]oxazin-6-yl）-N＇,N＇- disubstituted urea compounds were designed and synthesized. Their structures were confirmed by IR, ^1H NMR and LC/MS spectra.The primary bioassay results showed that some title compounds had some herbicidal activities, for example, compound 4e and 4h exhibited more than 70% herbicidal activity against, Amaranthus spinosus at the rate of 75 g a.i./hm^2.
