  Design, synthesis and pharmacological evaluation of 3-benzylazetidine-2-one-based human chymase inhibitors

  摘要：

  3-Benzylazetidine-2-one derivatives were designed and evaluated as a novel series of chymase inhibitors. Structure-activity relationship studies of 3-benzylazetidine-2-ones led to compounds 23, which exhibited 3.1 nM inhibition of human chymase and enhancement of stability in human plasma (t(1/2) 6 h).

  通过重氮烷烃的原位形成和捕获合成酯

  摘要：

  已经开发了用于通过羧酸原位形成和捕获重氮烷烃以形成酯的通用方法。该方法适用于使用重氮化合物的各种羧酸，重氮化合物是由苯甲醛和芳基酮的形成的。使用红外光谱（ReactIR）进行原位反应监测可证明将slow缓慢添加到氧化剂和羧酸的混合物中可避免重氮化合物的积累。此方法无需分离重氮化合物即可从简单的前体安全制备酯。

• A Facile Route to Aryl Amines: Nucleophilic Substitution of Aryl Triflates
  作者：Laurent Schio、Guy Lemoine、Michel Klich

  DOI：10.1055/s-1999-2886

  日期：——

  The aromatic nucleophilic substitution (SNAr) between aryl triflates and secondary amines has been studied. In the absence of solvent, the reaction proceeds at room temperature for nitro and cyano activated aryl triflates and requires higher temperatures in the case of carboxy activation. Variable triflate reactivity could be explained in terms of frontier molecular orbital theory. This methodology

  已经研究了芳基三氟甲磺酸酯和仲胺之间的芳香亲核取代 (SNAr)。在没有溶剂的情况下，硝基和氰基活化的芳基三氟甲磺酸酯的反应在室温下进行，在羧基活化的情况下需要更高的温度。可变三氟甲磺酸酯反应性可以用前沿分子轨道理论来解释。该方法已用于合成取代的哌啶基吡啶。
