• Nickel-Catalyzed Amide Bond Formation from Methyl Esters

  reactions, the synthesis of amide bonds is accomplished primarily by wasteful methods that proceed by stoichiometric activation of one of the starting materials. We report a nickel‐catalyzed procedure that can enable diverse amides to be synthesized from abundant methyl ester starting materials, producing only volatile alcohol as a stoichiometric waste product. In contrast to acid‐ and base‐mediated amidations

  尽管是最重要且经常进行的化学反应之一，酰胺键的合成主要通过浪费的方法完成，该浪费的方法是通过化学计量活化一种原料而进行的。我们报道了一种镍催化的方法，该方法可以使从丰富的甲酯原料中合成出各种酰胺，仅产生化学计量废品的挥发性醇。与酸和碱介导的酰胺化反应相反，该反应被认为是通过中性的交叉偶联型机理进行的，从而为直接，有效，化学选择性的合成开辟了新的机会。

  relationship (SAR) study focused on chemical modifications of the structure of the local anesthetic lidocaine, and indicated analogues having reduced anesthetic potency, but with superior potency relative to the prototype in preventing anaphylactic or histamine-evoked ileum contraction. From the SAR analysis, 2-(diethylamino)-N-(trifluoromethyl-phenyl) and 2-(diethylamino)-N-(dimethyl-phenyl) acetamides were

  目前的结构-活性关系（SAR）研究集中于局部麻醉利多卡因结构的化学修饰，并指出麻醉药效价降低，但与原型药相比在预防过敏或组胺引起的回肠收缩方面的效价更高。从SAR分析中，选择2-（二乙基氨基）-N-（三氟甲基-苯基）和2-（二乙基氨基）-N-（二甲基-苯基）乙酰胺作为最有前途的化合物。提供了关于非麻醉性利多卡因衍生物作为变应性综合征药物发现模板的适用性的新见解。

  The present invention relates to lidocaine derived compounds, which present less anesthetic activity than lidocaine itself, but with more anti-inflammatory and spasmolytic activity than said lidocaine as well as pharmaceutical compositions with at least one of these compounds or a salt of those as active principle and to the use of such compositions to treat, prevent or inhibit atopic diseases including asthma, rhinitis, allergic urticaria, chronic lung inflammation associated with eosinophilia, following the example of atopic asthma and chronic intestinal inflammation, as colitis for instance. The pharmaceutical composition may be available in spray form, solution, suspension, emulsion destinated to be applied by nebulization, or in any of the pharmaceutical available forms for oral or injectable use.
