Abstract
本发明提供了一种制备具有通式I的吡啶二羧酸酯化合物的单罐法，这是通过将烷基乙烯基醚依次与Vilsmeier反试剂、草乙酸酯和氨源缩合而实现的。
Description
吡啶-2，3-二羧酸及酯是许多生物活性产物，尤其是咪唑啉酮除草剂的基本原料，例如美国专利4,758,667。通过氧化合适的喹啉或烷基吡啶前体来制备吡啶-2，3-二羧酸酯衍生物的已知方法常受困于以下因素：使用昂贵的氧化剂，例如KMnO4、H2Cr2O、SeO2等；反应周期长，例如在使用臭氧、电解法等的反应中；不需要的副反应，例如脱羧反应、N-氧化物的形成等。所以，人们一直在寻找一种制备所需的吡啶-2，3-二羧酸酯衍生物的新方法。
已经发现，通过将合适的烷基乙烯基醚依次与Vilsmeier试剂、草乙酸酯和氨源缩合，可以方便地获得一种制备吡啶-2，3-二羧酸酯衍生物的快速单罐法。
本发明提供了一种制备具有通式I的吡啶-2，3-二羧酸酯衍生物的高效方法
其中，R1是H或可被C1-C4烷氧基或卤素取代的C1-C4烷基；R2和R3各自独立地是C1-C6烷基，优选甲基或乙基。该方法包括：
1)具有通式II的烷基乙烯基醚化合物与至少一摩尔当量的Vilsmeier试剂任选地在第一溶剂中形成第一中间体；
其中通式II化合物是顺式异构体、反式异构体或其混合物，R是C1-C4烷基，R1的定义与通式I中的相同；
2)所述的第一中间体与至少一摩尔当量的具有通式III的草乙酸酯，在至少2摩尔当量碱存在下形成第二中间体；其中R2和R3的定义与通式I中的相同；
3)第二中间体与氨源任选地在第二溶剂中形成具有通式I的吡啶二酯产物。
通式I化合物可用于制备咪唑啉酮除草剂。
在制备吡啶-2，3-二羧酸酯衍生物的的已知方法中，包括降解法，例如适当取代的喹啉或烷基吡啶前体的氧化。但是，氧化反应过程通常成本高而且危险。可喜的是，已发现，通过将合适的通式II烷基乙烯基醚与Vilsmeier试剂、通式III草乙酸酯和氨源依次缩合，可以在一个反应罐中高效制得吡啶-2，3-二羧酸酯衍生物。该反应如流程图I所示，其中X-表示Cl-或PO2Cl2 -。
流程图I
根据本发明的方法，顺式、反式或其混合物形式的通式II烷基乙烯基醚与至少一摩尔当量Vilsmeier反应剂或可性地在第一溶剂中形成第一中间体插烯亚胺盐(vinylogous imidate salt)，后者然后与至少一摩尔当量的通式III草乙酸酯在至少二摩尔当量碱(以有机胺碱为佳)存在下形成第二中间体(亚铵盐(iminium salt))，任选地(且是较好的)在第二溶剂中与氨源形成所需的通式I吡啶-2，3-二羧酸酯衍生物。
Vilsmeier试剂在说明书和权利要求书中指二甲基甲酰胺与活化剂(例如草酰氯、碳酰氯、磷酰氯、亚硫酰氯等)原地反应而生成的产物，可以表示为通式IV的亚铵盐或其插烯物，其中X-表示Cl-或PO2Cl2 -。
卤素在说明书和权利要求书中指Cl、Br、I或F。
适合用作本发明第一溶剂的溶剂是任何惰性有机溶剂，例如烃类，如己烷、戊烷、庚烷等；卤化烃，如二氯甲烷、氯仿、二氯乙烷等，以二氯乙烷或二氯甲烷为佳；芳香烃，如苯、甲苯、二甲苯等；卤化芳香烃，如氯苯、邻二氯苯或其混合物。最好，反应在第一溶剂中进行，而且，最好，第一溶剂是卤化烃，例如二氯乙烷或二氯甲烷。
适用于本发明方法的碱是有机胺碱，例如三乙胺、吡啶、二甲基吡啶、N，N-二甲基哌啶、N-甲基吡咯烷酮等，以三乙胺或吡啶为佳。
适用于本发明方法的氨源是任何原地产生NH3的常规方法，其中包括氨气、铵盐等，以铵盐为佳，例如乙酸铵、氨基磺酸铵等。
适合用作本发明中的第二溶剂的溶剂是极性溶剂，例如水；醇，如乙醇、甲醇、丙醇、丁醇之类的C1-C4烷醇等，以乙醇为佳；有机酸，例如乙酸、丙酸之类C1-C4羧酸等，以乙酸为佳，或以上所述物质的混合物。
反应产物的形成速度一般与反应温度成正比。总的说来，低温将减慢反应速度而高温将加速反应。但是，温度不宜过高，这可能降低产品的得率和纯度。较好的温度范围是从0℃至120℃。
为了帮助理解本发明，给出以下实施例，为的是说明某些更具体的细节。本发明并不受实施例的限定，而仅由权利要求限定。NMR表示核磁共振。
