Description
技术领域
本发明涉及一种杀虫剂,尤其是涉及一种具有杀虫活性的N-取代噁二嗪类化合物,其制备方法和应用。
背景技术
噁二嗪类(oxadiazine)杀虫剂茚虫威(indoxacarb)是美国杜邦(Dupont)公司1992年开发的钠通道抑制广谱杀虫剂(W09211249),基于一种新的杀虫作用机制,即阻断神经细胞的钠离子通道,减少和常用杀虫剂(如除虫菊酯、有机磷以及氨基甲酸酯类杀虫剂)发生交互抗性的可能。茚虫威本身是一种前体杀虫剂,通过在昆虫体内代谢去除酰胺氮原子上的甲氧羰基(-COOCH3)后转化为活性化合物,在广谱范围内具有很高的杀虫活性而且融合了环境相容性好、对哺乳动物毒性低和对鸟类、鱼类以及益虫安全的优点,作为替代有机磷杀虫剂的理想品种之一。
茚虫威的先导化合物为苯甲酰脲类杀虫剂RH3421,Philips-Duphar公司在苯甲酰脲类杀虫剂1的基础上运用生物等排理论将1变为2,后来开发出环状结构3。在结构3中A,Z可为多种基团,并且可以同其他原子组成五元或六元环,为了便于合成环状结构3优化为4(PH60-42),可能由于残留的原因,不能满足登记的要求,没有最终工业化。
Ricard Jacobson博士(罗门哈斯公司)于1980年开始针对化合物4,通过结构优化发现化合物5(RH3421),RH3421不仅对鳞翅目、鞘翅目害虫有很好活性,在较低剂量下具有良好防治效果。作用机理新颖,是钠离子通道抑制剂,与苯甲酰脲类杀虫剂的机理完全不同。
由于RH3421具有特异性作用机理,杜邦公司Thomas Stevenson等人开始对RH3421类化合物进行结构优化,在RH3421和化合物6的基础上,将1位上的N原子和3位上的C原子交换,得到化合物7,合成了一些化合物,离体生测结果表明较好的活性。
化合物6的衍生结构8和9,可能是由于氢键的原因,杜邦公司的ThomasStevenson等就设想将化合物物9中的吡唑4位的一个取代基如R2和3位苯环邻位合环即变为结构为10和11的化合物。
通过离体生测发现化合物11的活性优于12b,同时还对吡唑开环化合物12b进行研究,并发现B1为CH2的活性要好于B1为CH2CH2的化合物,但合成的化合物的在活性谱以及残留活性方面均不令人满意,需要改进。通过结构活性分析他们发现环的大小直接影响到生物活性,并将化合物12a和12b进行了组合优化为13。通过研究发现化合物14在一定计量下对鳞翅目害虫具有很好的防治效果,但残留时间过长。
对大量的实验结果数据进行分析,经过进一步优化研究,发现15适宜的残留活性和较好的生态性能,但对哺乳动物具有相对较高的活性。经过进一步的研究发现了茚虫威的结构,尽管茚虫威本身活性较弱但可以被害虫快速代谢为活性很高的茚虫威的合成研制再次表明合成化学是一门取之不尽的技术。

步骤(2)所述的催化剂b为N,N-二异丙基乙胺、三乙胺、吡啶或哌啶。
步骤(2)所述的反应温度为20℃~60℃。
步骤(2)所得N取代噁二嗪类化合物采用重结晶方法进行分离纯化,或采用柱色谱分离的方法进行分离纯化,所述的重结晶方法采用的溶剂为甲醇、乙醇、异丙醇、乙酸甲酯、乙酸乙酯、乙腈、二氯甲烷、二氯乙烷、三氯甲烷、甲苯、石油醚中的一种或两种以上的混合剂。
一种N-取代噁二嗪类化合物的应用,该化合物用于制备杀虫剂,对粘虫的杀虫活性达到80%~100%。
与现有技术相比,本发明不断对结构(I)进行结构优化和改造,最终研究出一些新的具有高杀虫活性的N取代噁二嗪类化合物Y001-Y052。
本发明涉及有N取代噁二嗪类化合物SIOC-Y-(001-052)对水稻褐飞虱、粘虫(小菜蛾)、红蜘蛛、苜蓿蚜等4个虫靶标的室内生物活性测试表明:化合物SIOC-Y-(001-052)在普筛浓度500mg/L时,其中化合物SIOC-Y-006、014、038、041-043、046、047、049、051对粘虫显示出100%的杀虫活性,036、037、039对粘虫显示出80%的杀虫活性,但对其他3种虫靶标室内杀虫活性较差或无杀虫作用。其余化合物对4种虫靶标室内杀虫活性均较差或无。
活性化合物降低浓度进一步筛选,结果表明SIOC-Y-047对粘虫仍表现出较好的杀虫活性,在浓度20mg/L时杀虫活性仍为100%。其余化合物降低浓度活性明显降低,在浓度20mg/L下室内对粘虫杀虫活性较差或无杀虫作用。结果表明化合物SIOC-Y-047对粘虫和斜纹夜蛾的活性略差与茚虫威,但EC50属于同一数量级水平。

98%敌敌畏原油(张家港市新宇化工厂)、95%哒螨灵原药(安徽金泰农药化工有限公司)、95%丁硫克百威原药(浙江禾田化工有限公司)。86.5%茚虫威原药(浙江禾田化工有限公司)
1.2试验靶标
稻褐飞虱(Nilaparvata legen)、粘虫(Mythima separata)、小菜蛾(Plutellaxylostella)、红蜘蛛(Tetranychus cinnabarnus)、苜蓿蚜(Aphis medicagini)。以上虫种为室内常年累代饲养或从田间采集室内饲养多代虫种。
1.3仪器设备
电子分析天平、培养皿、移液枪、Potter喷雾塔、毛笔等。
1.4药剂处理
用分析天平(0.0001g)称取一定质量的原药,加含有0.1%吐温-80的溶剂(DMF),配制成1%制剂。称取一定质量的制剂,加蒸馏水(点滴法稀释用丙酮)稀释配制成测定所需浓度的药液。
根据创制农药生物活性评价SOP(杀虫剂卷),普筛浓度选择500mg/L。
1.5试验方法
1.5.1水稻褐飞虱筛选——培养皿苗虫定量喷雾法
将水稻苗用白石英沙固定于培养皿内,接用CO2麻醉3龄中期若虫,置于POTTER喷雾塔下喷雾。喷雾后用透明塑料杯罩住,标记后放于观察室内。72h后检查结果。以敌敌畏和空白CK为对照。
1.5.2粘虫筛选——浸苗饲喂法
将玉米叶在药液中充分浸润后自然阴干,放入培养皿中,接3龄中期幼虫,加盖标记后置于观察室内。72h后检查结果。以敌敌畏和空白CK为对照。
1.5.3小菜蛾筛选——浸渍法
将甘蓝片剪下,打孔成圆片,然后浸于药液中20s,放于Φ9cm塑料培养皿内(5片/皿),接小菜蛾2龄幼虫15头/皿,放一张滤纸,加盖。置于26℃室内培养,72h后检查结果。试验重复4次。以尖头镊子轻触虫体,无反应视为死虫。以敌敌畏和空白CK为对照。
1.5.4朱砂叶螨筛选——浸渍法
将蚕豆叶片打成叶碟,背面朝上放在小块棉花上,置于塑料培养皿内,加少量水,接朱砂叶螨成螨。待成螨于叶片上稳定后,将叶片在药液中充分浸润5s后迅速用吸水纸吸去叶片表面水滴,重新置于棉花上,风干。72h后检查结果。以哒螨灵和空白CK为对照。
1.5.5苜蓿蚜筛选——浸渍法
将蚕豆叶片剪去两端,背面朝上放在小块棉花上,置于塑料培养皿内,加少量水,接苜蓿蚜成蚜以产若蚜。24h后去除成蚜,继续培养2d后将叶片在药液中充分浸润5s后,重新置于棉花上,自然凉干。24h后检查结果。以丁硫克百威和空白CK为对照。
1.6试验统计和进筛标准
统计各个处理的死虫数和活虫数,计算死亡率(Abbott’s公式)。
2结果与分析
化合物SIOC-Y-(001-052)对水稻褐飞虱、粘虫(小菜蛾)、红蜘蛛、苜蓿蚜等4个虫靶标的室内生物活性筛选结果表明:化合物SIOC-Y-(001-040)在普筛浓度500mg/L时,SIOC-Y-006、014、038、039、041、042、043、046、047、049对粘虫显示出100%的杀虫活性,036对粘虫显示出80%的杀虫活性。进一步筛选时,0047对粘虫仍表现出较好的杀虫活性,在浓度100mg/L和20mg/L时杀虫活性仍为100%。因此,建议SIOC-Y-006、014、036、038、039、041、042、043、046、047、049进行下一步筛选验证;其它化合物对水稻褐飞虱、粘虫、朱砂叶螨、苜蓿蚜等4个虫靶标均无明显活性。(筛选试验结果见附表1)
