  Triazolobenzo- and triazolothienodiazepines as potent antagonists of platelet activating factor

  摘要：

  A series of [1,2,4]triazolo[4,3-alpha][1,4]benzodiazepines bearing an ethynyl functionality at the 8-position and the isosteric thieno[3,2-f][1,2,4]triazolo[4,3-alpha][1,4]diazepines were prepared and evaluated as antagonists of platelet activating factor. The effects of substitution were explored in in vitro and in vivo test systems designed to measured PAF-antagonistic activity. Results are discussed and compared with previously published data. Many of the compounds had activity superior to WEB 2086, compound 1. In general, the thieno analogues exhibited better oral activity than the corresponding benzodiazepines. The duration of activity upon oral administration was modulated by the substitution on the acetylenic side chain. Compounds 71 and 81 were selected for further pharmacological evaluation as a result of their good oral potency and exceptionally long duration of action.

• Palladium-Catalyzed Trimethylenemethane Cycloaddition of Olefins Activated by the σ-Electron-Withdrawing Trifluoromethyl Group
  作者：Barry M. Trost、Laurent Debien

  DOI：10.1021/jacs.5b07573

  日期：2015.9.16

  α-Trifluoromethyl-styrenes, trifluoromethyl-enynes, and dienes undergo palladium-catalyzed trimethylenemethane cycloadditions under mild reaction conditions. The trifluoromethyl group serves as a unique σ-electron-withdrawing group for the activation of the olefin toward the cycloaddition. This method allows for the formation of exomethylene cyclopentanes bearing a quaternary center substituted by

  α-三氟甲基-苯乙烯、三氟甲基-烯炔和二烯在温和的反应条件下进行钯催化的三亚甲基甲烷环加成。三氟甲基用作独特的 σ-吸电子基团，用于将烯烃活化为环加成。该方法允许形成带有被三氟甲基取代的季中心的外亚甲基环戊烷，这是制药、农用化学品和材料工业感兴趣的化合物。在二烯系列中，环加成以 [3 + 4] 和/或 [3 + 2] 的方式进行以产生七元和/或五元环。这种转变极大地扩大了 TMM 环加成技术的范围，并提供了对反应机理的宝贵见解。

  Herein, we report an unusual α-methylene oxidation of N-substituted tetrahydroquinoline to lactams using the cyclometalated Ru(II)-complex as a catalyst. Cyclic-α-methylene C–H bonds are selectively oxidized under the reaction conditions even in the presence of α-methyl or reactive α-methylene C–H bonds. This methodology is also useful in the late-stage functionalization of pharmaceuticals. Mechanistic
