  Heteroaryl-Fused 2-Phenylisothiazolone Inhibitors of Cartilage Breakdown

  摘要：

  The synthesis, biological evaluation, and structure-activity relationships of a series of N-phenyl heteroaryl-fused isothiazolones are described. These isothiazolones have been shown to exhibit potent, dose-dependent inhibition of IL-1 beta-induced breakdown of proteoglycan in a cartilage organ culture assay. This effect is likely due to inhibition of MMP activation and a consequent reduction in MMP activity following IL-1 beta stimulation. Thus these compounds potentially represent simple, non-peptidic disease-modifying agents for the treatment of arthritic diseases. To examine the effects of structure on in vitro activity, three general features of the molecules were varied, substituents on the pendant N-phenyl group, the position of ring fusion to the isothiazolone, and substituents on the fused ring peri to the isothiazolone sulfur.

• Copper-Catalyzed Remote <i>para</i> -C−H Functionalization of Anilines with Sodium and Lithium Sulfinates
  作者：Shuai Liang、Michael Bolte、Georg Manolikakes

  DOI：10.1002/chem.201605101

  日期：2017.1.1

  A copper‐catalyzed, cross‐dehydrogenative coupling of anilines with sodium and lithium sulfinates was developed. By using a cooperative reaction system with Mn(OAc)3 as stoichiometric co‐oxidant a highly selective para‐functionalization of anilines was accomplished. Various functional groups were tolerated and the desired products were obtained in high yields. This method not only provides a novel

  已开发出铜催化的苯胺与亚磺酸钠和亚硫酸锂的交叉脱氢偶联反应。通过使用以Mn（OAc）3作为化学计量助氧化剂的协同反应系统，苯胺的高度选择性对官能化得以实现。耐受各种官能团，并以高收率获得所需产物。该方法不仅为芳基砜的合成提供了一种新颖的方法，而且还可能为开发铜催化的对位选择性CH官能团提供新的机会。
• Copper-Catalyzed Carboxamide-Directed <i>Ortho</i> Amination of Anilines with Alkylamines at Room Temperature
  作者：Qiong Li、Shu-Yu Zhang、Gang He、Zhaoyan Ai、William A. Nack、Gong Chen

  DOI：10.1021/ol500464x

  日期：2014.3.21

  In this report, a highly efficient method for the room temperature installation of alkyl amino motifs onto the ortho position of anilines via Cu-catalyzed carboxamide-directed amination with alkylamines is described. This method offers a practical solution for the rapid synthesis of complex arylamines from simple starting materials and enables new planning strategies for the construction of arylamine-containing pharmacophores. A single electron transfer (SET)-mediated mechanism is proposed.
