Abstract
通式(I)的化合物显示杀虫活性。
式中R1代表氢原子或烷基;Q代表通式为
-CHR2-或-CHR3-CHR4-的连接基,其中R2代表
氢原子或烷基,R3代表氢原子或烷基,R4代表氢原
子或烷基;X代表氮原子或=CH-基,Z代表卤原
子。
Description
本发明涉及新型异噁唑甲基取代的杂环化合物,涉及其作为杀生物剂,特别是杀虫剂的应用,涉及含有这种化合物的杀生物组合物,以及涉及这种化合物的制备方法。本发明特别涉及N-(3-卤-5-异噁唑甲基)-2-硝基亚甲基-和-2-硝基亚氨基咪唑啉和嘧啶。
EP-A-0192060(Nihon)涉及下列通式的杂环化合物
式中:n代表0或1;R1,R2,R5和R6分别代表氢原子或烷基;R3和R4分别代表氢原子,羟基或烷基;
y代表氮原子或=
-R9基团,其中R9选自一个含下列各基的大基团,例如氢或卤原子,或羟基,烷氧基,苄氧基,或烷基;
R代表氢原子或烷基;
Z代表一个含有至少一个选自氧,硫和氮杂原子的五元或六元杂环,该杂环还含有至少一个选自一个含下列各基的大基团的取代基,例如卤原子,或烷基,卤烷基,硝基,氰基,烷氧基,烷硫基,烷亚磺酰基,烷磺酰基,链烯基,卤烷氧基,卤烷硫基,卤链烯基,酰氨基,卤酰氨基,烷酯基,氰硫基或炔烃基。
EP-A-0192060的意图是公开887个化合物,但仅有较少数化合物附有证明化合物已被制出的任何物理化学数据。EP-A-0192060的宽权利要求包括本发明的N-(3-卤-5-异噁唑甲基)-2-硝基亚甲基-和-2-硝基亚氨基咪唑啉和嘧啶,另外,在164页,以实施例522-524的形式,举出三个这类化合物的结构,像下列那样,几个另外的3-取代-5-异噁唑甲基类似物:
另外,在188页,以实施例806的形式又举出这一化合物结构,但不带分析数据。
因此,就任何N-(3-卤-5-异噁唑甲基)-2-硝基亚甲基-和-2-硝基亚氨基咪唑啉和嘧啶而言没有举出任何分析数据。另外,没有举出生理活性数据。因此它们被认为只不过是书面上的实施例。
所以N-(3-卤-5-异噁唑甲基)-2-硝基亚甲基-和-2-硝基亚氨基咪唑啉和嘧啶不能被认为是由EP-A-0192060正式公开。
在Nihon的申请中实施例6,519和529的显然已制出的3-甲基和3-三氟甲基-异噁唑甲基化合物已经制成并试验,但已经发现,此化合物在消灭某些有害生物方面活性小于对应的本发明的3-卤-5-异噁唑基化合物。
按照本发明的第一种形态,本发明提供一种通式Ⅰ的化合物
式中R1代表氢原子或烷基;Q代表通式为-CHR2-或-CHR3-CHR4-的连接基,其中R2代表氢原子或烷基,R3代表氢原子或烷基,R4代表氢原子或烷基;
X代表氮原子或=CH-基团;
Z代表卤原子。
上述烷基较好是C1-4烷基,最好是甲基。
R2较好是甲基,最好是氢原子。
R3最好是氢原子。
R4最好是氢原子。
Q最好是通式为-CHR2-的基团,其中R2的定义如上所述。
X最好是=CH-基团。
Z较好是溴或氯原子,最好是氯原子。
按照本发明的第二种形态,本发明提供一种通式Ⅰ的化合物的制备方法,该方法包括使通式Ⅱ的化合物与通式Ⅲ的化合物,或与通式Ⅳ的化合物反应:
式中Z,R1和Q的定义如上,R5基团分别代表C1-4烷基,或苄基。两个R5基团较好是相同的C1-4烷基,最好是甲基。
该反应适合在惰性溶剂和升高的温度下进行。当使用通式Ⅲ的反应物来制备通式Ⅰ的硝基亚甲基化合物时,恰当的溶剂是链烷醇,例如乙醇。该反应适合在升高的温度,最好是回流温度下进行。当使用通式Ⅳ的反应物来制备通式Ⅰ的硝基亚氨基化合物时,恰当的溶剂是水。该反应适合在升高的温度,最好是70-90℃下进行。
通式Ⅱ的化合物的制法可以是,使通式Ⅴ的化合物与通式Ⅵ的化合物反应:
式中Z,R1和Q的定义如上,R6是卤原子,较好是氯原子,最好是溴原子。这一反应适合在极性有机溶剂,例如乙腈中进行。反应温度最好是0-40℃。
通式Ⅱ的化合物是新型的,该化合物及其制备方法构成本发明的另一种形态。
通式Ⅴ的化合物的制法可以是,形成一种反应混合物,该反应混合物包含一种通式Ⅶ的化合物,一种碱金属碱和一种通式Ⅷ的化合物
式中Z和R6的定义如上,R7是卤原子,最好是氯或溴。R7和Z最好是相同的。该反应适合在惰性有机溶剂中进行,例如一种芳烃,例如甲苯,一种酯类,例如乙酸乙酯,一种卤化烷烃,例如二氯甲烷,或者一种醚,例如二甲醚。该反应最好是0-50℃的温度下进行。
通式Ⅶ的化合物可借助乙醛酸醛肟的控制卤化来制备。可行的卤化方法是:用计算量的N-氯代琥珀酰亚胺,N-溴代琥珀酰亚胺,次氯酸叔丁酯在一种合适的惰性溶剂中卤化,例如二甲醚之类的醚;或者用分子氯或溴在一种合适的惰性溶剂中卤化,例如二氯甲烷之类的卤代烃。反应温度适合在0-30℃,只是在用N-氯代琥珀酰亚胺时50-70℃的温度是合适的。通式Ⅶ的化合物最好不经分离即用于下一工序来形成通式Ⅴ的化合物。
关于通式Ⅴ的化合物的制备,可进一步参考Synthetic Communications,18(10)P.1171-1176(1988)。
