Description

作为除草剂的4-苯氧基香豆素
本发明涉及控制单子叶杂草生长的方法,本发明也涉及用作除草剂的4-(2,6-二取代苯氧基)香豆素衍生物及其制备方法。
选择性地控制杂草的生长是全世界作物生产中的一个经常性的问题,特别在有诸如禾本科作物的单子叶作物存在时控制单子叶杂草的生长尤为烦人。所述的杂草不仅在使禾本科作物繁殖的相同或相似种植条件下会繁殖,而且对控制这些杂草最有效的除草剂也会对禾本科作物产生植物毒性作用。因此,目前一直在寻找在种植禾本科作物时选择性控制不需要的单子叶杂草的新的有效方法。
本发明的一个目的是提供在包括单子叶作物的植物存在下有效地控制单子叶杂草、且对所述作物无害的方法。
本发明的再一个目的是提供在作物生产中,特别是在禾本科作物生产中用作选择性除草剂的4-(2,6-二取代苯氧基)香豆素衍生物。
本发明的有利之处在于4-(2,6-二取代苯氧基)香豆素衍生物在水稻种植的条件下可以尤为有效地控制青草和其它单子叶杂草的生长,同时对水稻没有或几乎没有植物毒性作用。
本发明涉及控制单子叶年生、多年生和水生植物的方法,包括给含有所述植物的种子或其它繁殖器官的土壤或水施加除草有效量的式I化合物:(I)其中

本发明也涉及在作物存在下选择性地控制单子叶杂草,它包括给杂草种子或繁殖器官所处的且已种植或移植了作物的土壤或水中施加除草有效量的如上所述的式I化合物。
本发明进一步涉及式I的除草化合物、含有式I化合物的组合物以及制备所述化合物的方法。
由于顽固的和传播性杂草的存在可使作物生产降低30%~60%。在各种作物,特别是禾本科作物,种植和收成中,特别的杂草问题是单子叶杂草,如雨久花属(monochoria)、慈菇属(saggitaria)、莎草属和青草,这是在生产如谷类、小麦、大麦、稻、燕麦之类的禾本科作用中的持久性的问题。更具体地说,种稻时,诸如稗和水草之类的杂草的存在和繁殖会明显降低谷物的得率和质量。由于控制单子叶杂草的除草剂一般对禾本科作物有潜在的植物损伤,从而使问题复杂化。
现已发现,给杂草种子或繁殖器官所处的土壤或水中施加式I的4-苯氧基香豆素衍生物可以有效地控制诸如雨久花属、慈菇属、莎草科和青草之类的单子叶年生、多年生和水生杂草。
令人惊奇的是,在诸如玉米、小麦、大麦、稻、燕麦之类的禾本科作物存在下可以选择性地控制所述的单子叶杂草而对所述的作物几乎没有或完全没有植物毒性。有利的是,式I的4-苯氧基香豆素可在芽前施加于单子叶杂草,可在灌水的稻田中于移植后施加到水稻秧苗上,这样可以有效地控制杂草,而稻作物几乎不受或完全不受相当的伤害。
本发明的用作除草剂4-苯氧基香豆素是式I化合物:(I)其中
X和X′各自是卤素、C1~C4烷基或C2~C4链烯基;
W、Y和Z各自是O或S;
R是1~3个选自H、卤素、C1~C4烷基、C3~C6环烷基、C1~C4卤代烷基或C1~C4烷氧基的任何结合形式;

应当明白,R和R1代表苯环3、4和5位上(若为R)以及稠合苯环的5、6、7和8位上(若为R1)的取代基。在每种情况下,芳环可以在全取代或全部未取代的范围里(对于R1来说),(对于R的情况)可以被X和X’二取代。当苯环被X和X,代表二取代时,R指H。当式I的4-苯氧基香豆素的稠合苯环位置完全不被取代时,则R1代表H。
术语卤代烃基代表含有1至2n+1个卤素原子的烷基,CnH2n+1。卤原子是Cl、Br、F或I。
较好的式I化合物是那些其中X和X′各自是Cl、Br或CH3,W、Y和Z是O。更好的化合物是X和X’各自是Cl、Br或CH3;W、Y和Z是O;R是H,R1是1、2或3个卤素。C1~C4烷基、C1~C4卤代烷基、C1~C9烷氧基、C1~C4卤代烷氧基或NO2的化合物。最好的化合物是其中X和X’各自是Cl、Br或CH3;W、Y和Z是O;R是H,R1是5-C1~C4烷基、5-卤代、5-C1~C4卤代烷基或5-NO2的化合物。
可以从容易得到的式III的2-羟基乙酰苯或其式II的水杨酸前体制得式I的4-(2,6-二取代-苯氧基)香豆素化合物。用如Heimark等在the Journal of Labelled Compounds and Radiopharma-ceuticals,1986,Vol.23,No.2.中所述的标准文献操作,在甲基锂的存在下,可将式II的酸转化成相应的式Ⅲ的乙酰苯。在至少2摩尔当量诸如氢化钠之类的碱存在下使式III乙酰苯与碳酸乙酯反应可得式IV的4-羟基香豆素。使用诸如POCl3加清除剂胺的标准过程可以将所述的羟基香豆素转化成相应的式V的4-氯香豆素衍生物。式V的氯代香豆素然后与式VI的2,6-二取代苯酚或硫代苯酚反应,得到所需的式I产品,其中Y是氧(式Ia)。为了得到Y是S的式I产物(Ib),可将Ia的香豆素与Lawesson试剂或P2S5反应。反应流程如流程I所示。
                                  流程I
另一种方法是,将式II水杨酸转化成相应的式VII酰氯。如D.R.Buck等在Journal of Medicinal Chemistry,1975,Vol.18,No.4,391~394页中所述的,在碱的存在下用丙二酸二乙酯处理酰氯,形成中间体,后者可任意地在溶剂存在下经由加热的脱除羧乙氧基,得到所需的式IV的4-羟基香豆素。如上述流程I所示,可以将式IV羟基香豆素转化成式I的4-(2,6-二取代苯氧基)香豆素化合物。所述的反应顺序如流程II所示。
                                  流程II
Figure A9510759200161
也可以根据H.Cairns等在the Journal of Medicinal Chem-istry,1972,Vol.15,No.6.,pp.583~589,中所述的,通过用乙炔二羧酸二甲酯处理可从式VIII的酚得到式IX富马酸,这样也可有效地制备式I的4-(2,6-二取代苯氧基)香豆素除草剂。令人惊奇的是,用五氧化磷和甲磺酸的混合物处理式IX富马酸会高收率地生成式II的色酮-2-羧酸。然后,根据V.A.Zagorevskii和E.K.Orlova在Zhurnal Obschei Khimii,Vol.33,No.6,1963,pp.1857~1863.中所述,在催化量二甲基甲酰胺的存在下用亚硫酰氯处理可将式X中间体转化成式V氯代香豆素。这样制得的4-氯香豆素可以根据上述流程I制成所需的式I4-(2,6-二取代苯氧基)香豆素。反应顺序如流程III所示。
                                  流程III
本发明的4-苯氧基香豆素是式I的化合物,其中的X、X′、W、Y、R和R1如上所述,且条件是R1之一需至少是氢以外的基团。所述的化合物对于控制种种单子叶年生和多年生杂草是有效的除草剂。此外,这些化合物对生长在干地和湿地的杂草控制是有效的。以约0.006Kg/公顷~4.0Kg/公顷的施用率,较好的是以约0.06Kg/公顷~2.0Kg/公顷的施用率,可以得到有效的控制。当然,以高于4.0Kg/公顷的比率显然可用来有效地控制不需要的单子叶杂草,但是,由于过量除草剂会增高成本且对环境无益,故应避免使用高于所需有效水平的除草剂用量。
令人惊奇的是,现已发现本发明的式I苯氧基香豆新化合物是在作物生产中有用的选择性除草剂。特别是式I苯氧基香豆素化合物是在作物生产中有用的选择性除草剂。特别是式I化合物在诸如玉米、小麦、燕麦、大麦、稻之类禾本科作物存在下可以有效地控制如青草、莎草、雨久花属和慈菇属的传播性单子叶杂草。特别是,式I化合物对于在灌水的稻田中有移植稻的存在下控制青草杂草尤其有价值。
在农业实践中,本发明的化合物以包括农业上可接受的固体或液体载体和除草有效量的式I的苯氧基香豆素化合物的组合物形式施用。例如,可以诸如悬浮浓缩物、水剂浓缩物、可乳化的浓缩物、浓缩乳剂等之类的液体组合物形式,或以诸如可湿性粉未、可分散的颗粒、颗粒制剂、粉剂等的固体组合物形式施用。可望将本发明的化合物与其它的杀虫按有顺序地或同时地作为罐装混合物或单一组合物进行合并使用。特别是式I的苯氧基香豆素可与诸如氨碳酰脲、磺酰脲、二硝基苯胺、咪唑啉酮、硫代氨基甲酸酯、吡咯并嘧啶磺酰胺、α-卤代乙酰氨之类的共-除草剂合并使用。特别的例子是包括式I的苯氧基香豆素和氨磺酰脲、二硝基苯胺、磺酰脲或咪唑啉酮合并使用。虽然不是必需的,包括式I的化合物和共-除草剂的合并除草剂还可以包括其它组份,如,肥料、诸如表面活性剂、乳化剂、去沫剂、染料、增量剂之类的惰性辅剂。
为了更清楚地理解本发明,下面列出特定的实施例。所述的本发明及权利要求书并不只被这些实施例的范围所限定。确实,本技术领域的技术熟练者可从下列实施例和前面的叙述中作出除前所例举和叙述以外的本发明的种种改进。这类改进仍属本发明的权利要求范围内。1H、13C、19FNMR依次指质子、碳和氟核磁共振谱、IR是指红外光谱,HPLC指高效液相色谱。

按下列方法测定在移植后施药条件下的芽前除草活性和对稻作物的毒性,将杂草种子或块茎种在无排水孔的塑料容器内,它被种于淤泥沃土下的0.5cm处,4~6株两叶状态的稻禾(CV.Tebonnet)被移植入相同的容器内。塑料容器可以是32盎司,直径10.5cm或13cm×13cm占方,8cm深。在播种和移植后,将容器放在温室台上,使土壤保持3天浸透状态。在第3天,在容器中放水灌至土壤表面上的2~3cm处。灌水的土壤表面然后用选择好的丙酮水溶液(20/80V/V水/丙酮)混合物和足量的能达到约4.0Kg/公顷至0.50Kg/公顷活性组份的试验化合物进行处理。处理后,将容器放在温室台上,加水使其水平面保持在土壤表面2~3cm以上。
处理后的3~4周对植物作评估,并根据肉眼观察到的生长疏密度、大小、生气、颜色、生长变形及所有外观给除草作用分等级,等级系统如下所示。若再进行试验,则将数据平均,结果如表III所示。

在此实施例中,将Deluvian淤土(Toyokawa淤泥)放在100cm2×9cm(深)的塑料罐中。向罐中加水至土壤表面的水平处,并将混合物拌3cm深处。
然后将单子杂草和块茎种入罐中土壤0~2cm深处,移入2.5叶片状态的稻植物,将犁植物种在约3cm土壤深处。然后向所有罐中加水至3cm深,并在试验期间保持3cm深。在移植入稻植物和播入杂草种子和块茎后按实施例196所述的方法施加试验化合物。然后将罐子放在温室台上,按常规方法护理。处理后于20和30天时评估试验。处理后30天评估的结果如表IV所示。所用的等级系统与实施例196所述的相同。
