Abstract
一种除草剂组合物,其中包括载体和作为活性成分的通式为
的化合物,式中取代基的定义见说明书式Ⅰ的某些化合物是新的。
Description
本发明涉及某些2,6-取代吡啶,其制备方法除草剂组合物和作为除草剂的用途。
吡啶类和吡啶衍生物有许多用途、例如可作为药品、农药(除草剂、杀螨剂、驱虫剂、驱鸟剂)、饲料添加剂、溶剂、试剂、中间体和用于聚合物及纺织工业的化学品。各种2,6-二芳氧基-或2,6-二芳基甲氧基-吡啶衍生物已被研究用作这些用途,这些化合物的中央吡啶环上常有另外的取代基。
EP-A2-180188涉及2-羟基吡啶衍生物,例如2,6-二羟基吡啶,用作增加5-氟代尿嘧啶和有关化合物抗癌活性的增效剂。透露了2,6-二苄氧基-3-氯代吡啶的制备和脱苄基反应。在J.Biol.Chem.,72,卷247(23).7628-7633页中(涉及2,3,6-三羟基吡啶的合成和2,6-二羟基吡啶氧化产物的累积和部分特性),公开了3-溴-2,6-二苄氧基吡啶同异丙基溴的格林那反应。既没有公开2,6-二苄氧基-3-氯代吡啶的也没有公开其溴代类似物的生物活性。
法国专利说明书1527714号涉及含-2,6位相连的吡啶基团的聚醚。在该说明书中公开了2,6-二(3-甲基苯氧基)-吡啶。US-A-4830846涉及利用受阻吡啶通过热断裂分离无水HCl和HBr的方法,其中受阻吡啶的一个例子是2,6-二苯氧基吡啶。这些芳氧基吡啶的生物活性仍然未披露。
除了在JP-A-63250324、EP-A-180188和J.Med.Chem,10(2)320-325页,所有的医学研究刊物中提到的外,2,6-二苯氧基吡啶的二苄氧基类似物在US-A-3535328和作为US-A-3687959的分案申请中建议作为除草化合物的一个实例来制备。两篇文本主要涉及酰胺基或氨基硫代乙氧基衍生物的除草、杀真菌对US-A-3535328中要求的化合物)、杀线虫和杀昆虫活性。对公开的2,6-二苄氧基吡啶未给出除草活性数据。
对现在讨论的2,6-二苄氧基吡啶及其2,6-二苯氧基吡啶类似物的除草性评价表明,这些化合物主要对典型的阔叶植物物种在出苗后的叶喷施中具有除草活性,但对典型的草类植物物种很少或无出苗后活性,并完全没有出苗前除草活性。
令从吃惊的是现已发现2,6-二苯氧基吡啶和2,6-二苄氧基吡啶的某些取代形式,以及有关的不对称2-苯氧基-6-二苄氧基-吡啶具有明显不同的活性谱,而且不仅对在叶喷施中的阔叶植物具有高活性,并且对草类植物特别是对重要的杂草、稗草也有显著的作用,许多实例还对这两类植物在出苗前是有效的。
其中,每一n和m各自为0或1;
每一Ar1和Ar2各自代表芳基,至少Ar1和Ar2中之一被一个或多个相同或不同的卤原子、烷基、烷氧基、卤烷基和卤烷氧基取代;
R1代表氢原子、或具有1至4个碳原子的烷基、烷硫基和卤烷基,R2代表氢或卤原子,条件是至少R1和R2中之一代表氢原子。
除非另有指定,烷基可以是适当含达12个碳原子,优选含1-4个碳原子的直链或支链基团。卤烷基、烷基硫、烷氧基或卤烷氧基的烷基部分宜含1-4个碳原子,优选含1或2个碳原子。
卤素可以是氟、氯、溴或碘。卤烷基和卤烷氧基优选是单一、二-、或三-氟烷基和烷氧基,特别是三氟甲基和三氟甲氧基。
芳基优选是苯基。
式I化合物中的Ar1-(CH2)n-O-和Ar2-(CH2)m-O-部分可以相同或不同;因此,该化合物可以是对称或不对称的二芳氧基吡啶或二芳基甲氧基吡啶,或可以是芳氧基芳基甲氧基吡啶。
n和m中之一优选是1,另一个是0或1,但每个n和m更优选都是1。

R1优选是氢原子或甲基、甲硫基或三氟甲基。特别优选的是氢或甲基。
R2宜为氢原子或氯原子,特别适宜的是氢原子。
根据通式I使用的符号,优选的化合物落入以下类属;
(i)n是0;m是0;R1和R2各自代表氢原子;Ar1代表三氟甲苯基,特别是3-三氟甲苯基;Ar2代表未取代或被氯、或三氟甲基取代的苯基;
(ii)n是0;m是1;R1 1和R2各自表示氢原子,Ar1表示取代的苯基,特别是3-三氟甲苯基;Ar2代表未取代的苯基或氟取代的苯基。

大多数通式I化合物是新的。因此,本发明提供通式I化合物,在下列条件下,其中的n、m、Ar1、Ar2、R1和R2具有上述意义:
a)当n和m都为0时,每一Ar1和Ar2都分别不表示3-甲基苯基;和
b)当n和m都为1时,R2不表示氯或溴原子。
通式I化合物可以通过对通常制备取代吡啶化合物的方法适当修改而获得。例如,基本方法是在一溶剂中和适当的高温下,理想的是在回流下,使适当醇的金属盐同适当的2,6-二卤代吡啶进行反应。制备对称的吡啶化合物时采用盐与吡啶的摩尔比至少为2∶1,一步完成反应。制备不对称的I式化合物时,以两步过程将两个取代物分别加入。
因此,本发明提供制备式I化合物的方法,该方法包括:
a)为得到Ar1和Ar2是相同的式I化合物,将通式为
或
b)为得到Ar1和Ar2是不同的式I化合物,将式II化合物同式III的2,6-二卤代吡啶以摩尔比为1∶1进行反应,得到的产物再同通式为IV
Ar2(CH2)mOH (IV)的化合物的金属盐以摩尔比至少为1∶1进行反应,IV中的Ar2和n如上定义。每一反应阶段在有机溶剂存在下进行。
合适的式II醇的金属盐是碱金属盐,例如钠盐或钾盐,它通过醇与适当的金属碱(如金属碳酸盐或氢化物)反应方便地得到。优选的金属盐是用氢化钠产生的钠盐。
反应中所用的有机溶剂可根据所涉及的反应物性质而选择。一般说,任一极性有机溶剂是适宜的,例如,二甲基甲酰胺和四氢呋喃。
Hal1和Hal2两者相同是合适的,每一个表示氯原子或溴原子。
如果需要的话,制备的式I化合物可以用传统的方法分离和提纯。
式II、III和IV化合物通常是已知的和/或可用标准方法方便地制得的。
本发明还提供将式I化合物作为除草剂的用途。根据本发明,还提供消除场所中不需要的植物生长的方法,即用本发明的组合物或式I化合物处理场所。由于最有效的方式是叶面施用,所以适宜的场所是在作物地区中的植物,典型的作物是谷类。然而,对那些具有出苗前除草作用的化合物也可施用于土壤。活性成分使用的剂量范围例如,可以为0.01-10公斤/公顷,优选为0.1-1.0公斤/公顷。
尽管本发明所有化合物都对阔叶和窄叶植物具有有效活性,但n和m中至少一个为1的化合物,特别是在本发明中的苯氧基/苄氧基吡啶中,和更好的是二苄氧基吡啶表现出异常好的活性。
本发明还延伸到配制本发明的除草组合物的方法,该方法包括将式I化合物同至少一种载体配合。
在本发明的除草组合物中,优选至少有两种载体,其中至少一种是表面活性剂。
本发明组合物中的载体是同活性成分配制后有利于向要处理的场所施用,或有利于贮存、运输或处理的任何一种物质,该场所可以是一种植物、种子或土壤。载体可以是固体或液体,包括通常情况下是气体但已经压缩成液体的物质,以及通常用在配制除草组合物中的任何载体。根据本发明优选的组合物含有0.5-95%重量的活性组分。
适用的固体载体包括天然和合成粘土和硅酸盐,例如象硅藻土那样的天然二氧化硅;硅酸镁,例如滑石;硅酸铝镁,例如硅酸铝铁载体和蛭石;硅酸铝,例如高岭土、蒙脱土和云母;碳酸钙;硫酸钙;硫酸铵;合成的水合氧化硅和合成的硅酸钙或硅酸铝;元素,例如碳和硫;天然和合成树脂,例如苯并呋喃树脂,聚氯乙烯和苯乙烯聚合物和共聚物;固体聚氯代苯酚;沥青;腊和固体肥料,例如过磷酸盐。
适用的液体载体包括水;醇类,例如异丙醇和乙二醇;酮类,例如丙酮,甲乙酮,甲基异丁基酮和环己酮;醚类;芳烃或芳脂烃(ar-aliphatic)例如苯,甲苯和二甲苯;石油馏分,例如煤油和轻质矿物油;氯代烃,例如四氯化碳,全氯乙烯和三氯乙烷。也常使用各种液体的混合物。
农用组合物常以浓缩的形式配制和运输,在施用前由用户加以稀择。少量的表面活性剂作为载体的存在有利于稀释过程。因此,根据本发明配制的组合物中至少一种载体优选是表面活性剂。例如,组合物可至少含两种载体,至少其中一种是表面活性剂。
表面活性剂可以是乳化剂、分散剂或润湿剂;可以是非离子型的,也可是离子型的。适用的表面活性剂例子包括聚丙烯酸的钠或钙盐和木质素磺酸的钠或钙盐:分子中至少含12个碳原子的脂肪酸或脂族胺或酰胺同环氧乙烷和/或环氧丙烷的缩合产物;甘油、山梨糖醇、蔗糖或季戊四醇的脂肪酸酯;这些与环氧乙烷和/或环氧丙烷的缩合物;脂肪醇或烷基苯酚,例如对-辛基苯酚或对-辛基甲酚,同环氧乙烷和/或环氧丙烷的缩合产物;这些缩合产物的硫酸酯或磺酸盐;硫酸的分子中至少含10个碳原子的磺酸酯的碱金属或碱土金属盐,优选钠盐,例如,月桂基硫酸钠,仲烷基硫酸钠,磺化蓖麻油的钠盐和烷芳基磺酸钠如十二烷基苯磺酸钠;和环氧乙烷的聚合物和环氧乙烷同环氧丙烷的共聚物。
本发明的除草组合物也可含其它活性成分,例如:具有杀昆虫或杀真菌性能的化合物或其它除草剂。
