  Benzimidazole-2-carboxamides as novel NR2B selective NMDA receptor antagonists

  摘要：

  A novel series of benzimidazole-2-carboxamide derivatives was prepared and identified as NR2B selective NMDA receptor antagonists. The influence of some structural elements, like H-bond donor groups placed on the benzimidazole skeleton and the substitution pattern of the piperidine ring, on the biological activity was studied. Compound 6a showed excellent analgetic activity in the mouse formalin test following po administration. (c) 2006 Elsevier Ltd. All rights reserved.

• Ruthenium-catalyzed oxidative decyanative cross-coupling of acetonitriles with amines in air: a general access to primary to tertiary amides under mild conditions

  Catalyzed by Ru and in the presence of air and nucleophiles such as amines or ammonia, activation of the C–CN bond could be easily achieved under mild conditions to produce primary to tertiary amides in good to excellent yields. The use of accessible and functional-group-tolerant starting materials, a cheap, low-loading and recyclable catalyst, ligand-free conditions and excellent product yields are

  在钌的催化下，在空气和亲核试剂（例如胺或氨）的存在下，在温和条件下可以很容易地实现C-CN键的活化，从而以良好或优异的产率生产伯酰胺至叔酰胺。该方法的优点是使用易接近且具有功能基团耐受性的起始原料，廉价，低载和可循环使用的催化剂，无配体的条件以及优异的产物收率。而且，与Ritter反应和水合方法相比，该新颖反应具有更广泛的应用范围。
