本发明的详细说明
定义和一般术语
现在详细描述本发明的某些实施方案,其实例由随附的结构式和化学式说明。本发明意图涵盖所有的替代、修改和等同技术方案,它们均包括在如权利要求定义的本发明范围内。本领域技术人员应认识到,许多与本发明所述类似或等同的方法和材料能够用于实践本发明。本发明绝不限于本发明所述的方法和材料。在所结合的文献、专利和类似材料的一篇或多篇与本申请不同或相矛盾的情况下(包括但不限于所定义的术语、术语应用、所描述的技术,等等),以本申请为准。
应进一步认识到,本发明的某些特征,为清楚可见,在多个独立的实施方案中进行了描述,但也可以在单个实施例中以组合形式提供。反之,本发明的各种特征,为简洁起见,在单个实施方案中进行了描述,但也可以单独或以任意适合的子组合提供。
除非另外说明,本发明所使用的所有科技术语具有与本发明所属领域技术人员的通常理解相同的含义。本发明涉及的所有专利和公开出版物通过引用方式整体并入本发明。
除非另外说明,应当应用本发明所使用的下列定义。出于本发明的目的,化学元素与元素周期表CAS版,和《化学和物理手册》,第75版,1994一致。此外,有机化学一般原理可参考"Organic Chemistry",Thomas Sorrell,University Science Books,Sausalito:1999,和"March's Advanced Organic Chemistry"by Michael B.Smith and Jerry March,John Wiley&Sons,New York:2007中的描述,其全部内容通过引用并入本发明。
除非另有说明或者上下文中有明显的冲突,本发明所使用的冠词“一”、“一个(种)”和“所述”旨在包括“至少一个”或“一个或多个”。因此,本发明所使用的这些冠词是指一个或多于一个(即至少一个)宾语的冠词。例如,“一组分”指一个或多个组分,即可能有多于一个的组分被考虑在所述实施方案的实施方式中采用或使用。
术语“包含”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。
“立体异构体”是指具有相同化学构造,但原子或基团在空间上排列方式不同的化合物。立体异构体包括对映异构体、非对映异构体、构象异构体(旋转异构体)、几何异构体(顺/反)异构体、阻转异构体,等等。
“对映异构体”是指一个化合物的两个不能重叠但互成镜像关系的异构体。
“非对映异构体”是指有两个或多个手性中性并且其分子不互为镜像的立体异构体。非对映异构体具有不同的物理性质,如熔点、沸点、光谱性质和反应性。非对映异构体混合物可通过高分辨分析操作如电泳和色谱,例如HPLC来分离。
本发明所使用的立体化学定义和规则一般遵循S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-Hill Book Company,New York;and Eliel,E.and Wilen,S.,“Stereochemistry of Organic Compounds”,John Wiley&Sons,Inc.,New York,1994中的描述。
许多有机化合物以光学活性形式存在,即它们具有使平面偏振光的平面发生旋转的能力。在描述光学活性化合物时,使用前缀D和L或R和S来表示分子关于其一个或多个手性中心的绝对构型。前缀d和l 或(+)和(-)是用于指定化合物所致平面偏振光旋转的符号,其中(-)或l表示化合物是左旋的。前缀为(+)或d的化合物是右旋的。一种具体的立体异构体是对映异构体,这种异构体的混合物称作对映异构体混合物。对映异构体的50:50混合物称为外消旋混合物或外消旋体,当在化学反应或过程中没有立体选择性或立体特异性时,可出现这种情况。
本发明公开化合物的任何不对称原子(例如,碳等)都可以以外消旋或对映体富集的形式存在,例如(R)-、(S)-或(R,S)-构型形式存在。在某些实施方案中,各不对称原子在(R)-或(S)-构型方面具有至少50%对映体过量,至少60%对映体过量,至少70%对映体过量,至少80%对映体过量,至少90%对映体过量,至少95%对映体过量,或至少99%对映体过量。
依据起始物料和方法的选择,本发明化合物可以以可能的异构体中的一个或它们的混合物,例如外消旋体和非对应异构体混合物(这取决于不对称碳原子的数量)的形式存在。光学活性的(R)-或(S)-异构体可使用手性合成子或手性试剂制备,或使用常规技术拆分。如果化合物含有一个双键,取代基可能为E或Z构型;如果化合物中含有二取代的环烷基,环烷基的取代基可能有顺式或反式构型。
所得的任何立体异构体的混合物可以依据组分物理化学性质上的差异被分离成纯的或基本纯的几何异构体,对映异构体,非对映异构体,例如,通过色谱法和/或分步结晶法。
可以用已知的方法将任何所得终产物或中间体的外消旋体通过本领域技术人员熟悉的方法拆分成光学对映体,如,通过对获得的其非对映异构的盐进行分离。外消旋的产物也可以通过手性色谱来分离,如,使用手性吸附剂的高效液相色谱(HPLC)。特别地,对映异构体可以通过不对称合成制备。
像本发明所描述的,本发明的化合物可以任选地被一个或多个取代基所取代,如上面的通式化合物,或者像实施例里面特殊的例子,子类,和本发明所包含的一类化合物。应了解“任选取代的”这个术语与“取代或非取代的”这个术语可以交换使用。一般而言,术语“取代的”表示所给结构中的一个或多个氢原子被具体取代基所取代。除非其他方面表明,一个任选的取代基团可以在基团各个可取代的位置进行取代。当所给出的结构式中不只一个位置能被选自具体基团的一个或多个取代基所取代,那么取代基可以相同或不同地在各个位置取代。具体地,“一个或多个”的实例是指1、2、3、4、5、6、7、8、9或10个。其中所述的取代基可以是,但并不限于,氘,氟,氯,溴,碘,氰基,羟基,硝基,氨基,羧基,烷基,烷氧基,烷氧基烷基,烷氧基烷氧基,烷氧基烷氨基,芳氧基,杂芳环氧基,杂环基氧基,芳基烷氧基,杂芳环烷氧基,杂环基烷氧基,环烷基烷氧基,烷氨基,烷氨基烷基,烷氨基烷氨基,环烷基氨基,环烷基烷氨基,烷硫基,卤代烷基,卤代烷氧基,羟基取代的烷基,羟基取代的烷氨基,氰基取代的烷基,氰基取代的烷氧基,氰基取代的烷氨基,氨基取代的烷基,烷基酰基,杂烷基,环烷基,环烯基,环烷基烷基,杂环基,杂环基烷基,杂环基酰基,芳基,芳基烷基,芳氨基,杂芳环,杂芳环烷基,杂芳环氨基,酰胺基,磺酰基,氨基磺酰基等等。
另外,需要说明的是,除非以其他方式明确指出,在本发明中所采用的描述方式“各…独立地为”与“…各自独立地为”和“…独立地为”可以互换,均应做广义理解,其既可以是指在不同基团中,相同符号之间所表达的具体选项之间互相不影响,也可以表示在相同的基团中,相同符号之间所表达的具体选项之间互相不影响。
在本说明书的各部分,本发明公开化合物的取代基按照基团种类或范围公开。特别指出,本发明包括这些基团种类和范围的各个成员的每一个独立的次级组合。例如,术语“C 1-C 6烷基”或“C 1-6烷基”特别指独立公开的甲基、乙基、C 3烷基、C 4烷基、C 5烷基和C 6烷基。

又另一方面,本发明提供一种本发明所述化合物或本发明所述组合物在农业中作为除草剂的应用。
又另一方面,本发明提供一种使用本发明所述化合物或本发明所述组合物防治杂草的方法。
本发明化合物的组合物和制剂
本发明的化合物一般可用作组合物即制剂中的除草剂活性成分,所述组合物即制剂具有至少一种用作载体的附加组分,所述附加组分选自表面活性剂、固体稀释剂和液体稀释剂。选择所述制剂或组合物成分,以与所述活性成分的物理特性、施用方式和环境因素(如土壤类型、湿度和温度)相一致。
有用的制剂包括液体组合物和固体组合物。液体组合物包括溶液(包括乳油)、悬浮液、乳液(包括微乳液和/或悬乳液)等,它们可以任选地被稠化成凝胶。水性液体组合物的一般类型为可溶性浓缩物、悬浮液浓缩物、胶囊悬浮液、浓缩乳液、微乳液和悬乳液。非水性液体组合物的一般类型为乳油、可微乳化的浓缩物、可分散浓缩物和油分散体。
固体组合物的一般类型为粉剂、粉末、颗粒、粒料、球粒、锭剂、片剂、填充薄膜(包括种子包衣)等,它们可以是水分散性的(“可润湿的”)或水溶性的。由成膜溶液或可流动的悬浮液形成的膜和包衣尤其可用于种子处理。活性成分可被(微)胶囊包封,并且进一步形成悬浮液或固体制剂;或者可将整个活性成分制剂胶囊包封(或“包覆”)。胶囊包封可以控制或延迟活性成分的释放。可乳化的颗粒结合了乳油制剂和干颗粒制剂两者的优点。高浓度组合物主要用作其它制剂的中间体。
可喷雾的制剂通常在喷雾之前分散在合适的介质中。将此类液体制剂和固体制剂配制成易于在喷雾介质(通常是水)中稀释的制剂。喷雾体积可以在每公顷约一升至几千升的范围内,但更典型地在每公顷约十升至几百升的范围内。可喷雾的制剂可在水槽中与水或另一种合适的介质混合,用于通过空气或地面施用来处理叶子,或者施用到植物的生长介质中。液体和干制剂可以直接定量加入到滴灌系统中,或者在种植期间定量加入到垄沟中。
所述制剂通常将包含有效量的活性成分、稀释剂和表面活性剂,总和为按重量计100%。
固体稀释剂包括例如粘土例如膨润土、蒙脱石、绿坡缕石和高岭土、石膏、纤维素、二氧化钛、氧化锌、淀粉、糊精、糖(例如乳糖、蔗糖)、硅石、滑石、云母、硅藻土、尿素、碳酸钙、碳酸钠和碳酸氢钠以及硫酸钠。典型的固体稀释剂描述于Watkins等人的Handbook of Insecticide Dust Diluents and Carriers,第2版,Dorland Books,Caldwell,New Jersey中。
