【摘要】 采用邻氨基酚为原料合成了一系列N-取代苯并噁唑啉酮类化合物和N-取代的苯并噁嗪啉酮类化合物,其化学结构经过1H核磁共振及元素分析确证。初步的生物活性试验结果表明,N-取代苯并噁唑啉酮类化合物具有一定的杀虫杀菌活性,其中化合物3b、4b、14b、19b在50mg/L浓度下对淡色库蚊的杀死率为100%,化合物20b、21b、24b、25b、26b、27b、30b在1000mg/L浓度下对朱砂叶螨的杀死率均达95%以上;N-取代苯并噁嗪啉酮类化合物具有良好的除草活性,如化合物3d,5d,6d,7d和8d在浓度为100mg/L时,对苋菜Ambrosia tricolor Linn的抑制率达90%。更多还原

【Abstract】 A series of novel N-substituted benzoxazol-2-ones and N-substituted benzoxazinone derivatives were designed and synthesized by the stating material 2-amino phenol.Their structures were confirmed by 1H NMR and elemental analysis.The preliminary bioassay showed that N-substituted benzoxazol-2-ones had insecticidal and fungicidal activities.The mortality of compounds 3b,4b,14b,19b to Culex pipiens pallens Coqillett at the concentration of 50 mg/L reached 100%,The mortality of compounds 20b,21b,24b,25b,26b,27b,30 b to Tetranychus cennbarinus at the concentration of 1 000 mg/L was all upwards 95%.Well,N-substituted benzoxazinone derivatives had herbicidal activity.The inhibition rate of 3d,5d,6d,7d and 8d to Ambrosia tricolor Linn at the concentration of 100 mg/L was up to 90%.更多还原
