  Copper-catalyzed highly regioselective 2-aryloxylation of 2,x-dihalopyridines

  摘要：

  2,x-Dihalopyridines reacted with phenols catalyzed by CuI/TMEDA in the presence of Cs2CO3 in DMSO at 110 degrees C under nitrogen atmosphere for 24 h to afford 2-aryloxypyridines in good to high yields except p-nitrophenol. To expand this methodology, a vanilloid receptor ligand used in treatments was prepared in good yield. This method has potential utility in the synthesis of pharmaceuticals, agrochemicals and even natural products. (C) 2012 Elsevier Ltd. All rights reserved.

  The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

  本发明涉及式(I)的官能化光反应化合物，特别适用于液晶对准材料。由于在特定分子系统中的不饱和键直接连接到两个不饱和环系统上附加了一个电子受体基团，因此在包含本发明的这些官能化光反应化合物的材料中可以实现异常高的光敏性、优异的对准性能以及良好的机械稳健性。

  Provided are a method of preparing a malononitrile oxime ether compound and an intermediate compound. The malononitrile oxime ether compound has a structure as shown in formula (VII), wherein W is selected from aryl or heteroaryl. The preparation method comprises steps: reacting a first raw material with a second raw material in the presence of a first solvent and a catalyst to obtain the intermediate compound, wherein the first raw material has a structure as shown in formula (IV), and the second raw material has a structure as shown in formula (V); and subjecting the intermediate compound as shown in formula (VI), and a dehydrant to a dehydrantion reaction in the presence of a second solvent to obtain the malononitrile oxime ether compound. In the preparation process for the intermediate, a cheaper cyanoacetamide is used as a raw material, the reaction conditions are mild. Moreover, the yield of the intermediate compound is high and the cost of the process is low. Furthermore, the required malononitrile oxime ether compound is obtained only through one-step dehydration reaction. Using the preparation method, is advantageous for improving the yield of malononitrile oxime ethers and reducing the cost of the process.
