• Enantioselective Hydrolysis of Functionalized 2,2-Disubstituted Oxiranes with Bacterial Epoxide Hydrolases
  作者：Andreas Steinreiber、Ingrid Osprian、Sandra F. Mayer、Romano V. A. Orru、Kurt Faber

  ether-oxygen to the stereogenic quaternary carbon center of the oxirane ring had a profound influence on the enantioselectivity, and several oxiranes were resolved with good to excellent selectivities. The enantiomerically enriched epoxides and vicinal diols thus obtained contain a useful “synthetic handle” in their side chain, which allows their use as building blocks in asymmetric synthesis.

  使用 11 种细菌菌株的环氧化物水解酶活性研究了带有各种氧官能团的 2,2-二取代环氧乙烷的生物水解。结果表明，活性和选择性强烈依赖于底物结构和生物催化剂。尽管具有游离羟基的底物没有被转化，但它们的类似物，被保护为醚，被广泛接受。这使得通过根据尺寸和极性正确选择醚组，可以方便地调制对映射性。发现醚-氧与环氧乙烷环的立体四元碳中心的距离对对映选择性有深远的影响，并且几种环氧乙烷以良好到极好的选择性分离。

  A new series of propionamide derivatives was developed as dual μ-opioid receptor agonists and σ1 receptor antagonists. Modification of a high-throughput screening hit originated a series of piperazinylcycloalkylmethyl propionamides, which were explored to overcome the challenge of achieving balanced dual activity and convenient drug-like properties. The lead compound identified, 18g, showed good analgesic

  开发了一系列新的丙酰胺衍生物作为μ阿片受体双重激动剂和σ1受体拮抗剂。对高通量筛选命中的修饰产生了一系列哌嗪基环烷基甲基丙酰胺，其被探索以克服实现平衡的双重活性和方便的类药特性的挑战。鉴定出的先导化合物18g在多种急性（爪压）和慢性（部分坐骨神经结扎）疼痛动物模型中显示出良好的镇痛效果，与羟考酮相比，胃肠道影响减轻。

  Ionic liquids based on 1,3-dialkylimidazolinium methanesulfonate have been used as effective reusable reaction media in the esterification of several carboxylate sodium salts with different alkyl halides. Products are easily isolated by extraction with ether, and the protocol is mild and green, compared to the existing methods based on toxic solvents. Proper ‘design’ of the ionic liquid allows us to
