  摘要：

  In this work, an effective, task specific, dicationic, podand-like ionic liquid was synthesized and applied to improve the capability features of click reaction. Moreover, to broaden the scope and decreasing the serious limitations of preparation methods of organic azides, a simple green procedure for the preparation of alkyl azides, the fundamental starting materials in click reactions, from alcohols under solvent-free conditions and microwave irradiation has been reported, for the first time.

• Anilides related to substituted benzamides. Potential antipsychotic activity of N-(4-amino-5-chloro-2-methoxyphenyl)-1-(phenylmethyl)-4-piperidinecarboxamide

  The substituted benzamides are used clinically both as antipsychotics and as stimulants of gastric motility. The antipsychotic effects are considered to be a consequence of their central dopamine antagonist properties, but there is evidence that the gastric stimulatory effects may be mediated by other mechanisms. Clebopride (3) is a substituted benzamide that although marketed for its stimulatory effects

  取代的苯甲酰胺在临床上既用作抗精神病药，又用作胃动力的兴奋剂。抗精神病作用被认为是其中央多巴胺拮抗剂特性的结果，但是有证据表明，胃刺激作用可能是由其他机制介导的。Clebopride（3）是一种取代的苯甲酰胺，尽管因其对胃蠕动的刺激作用而上市，但它也是有效的中枢多巴胺拮抗剂。已合成了酰胺键已被逆转的相应的苯胺化物BRL 20596（4a），发现其缺乏胃刺激活性。但是，有效的中枢多巴胺拮抗剂活性得以保留，表明苯甲酰胺和苯胺对中枢多巴胺受体具有相似的亲和力。讨论了在这些受体上苯甲酰胺和苯甲酰胺采用的构象的含义。也有证据表明，在这类受体上还有一个亲脂性结合位点，N-苄基最适合。

• Assembly of 4H-chromenes, imidazobenzothiazines and quinazolines via copper-catalyzed domino reactions using 2-halobenzyl tosylates as substrates
  作者：Mohamed A. Omar、Jürgen Conrad、Uwe Beifuss

  DOI：10.1016/j.tet.2014.06.071

  日期：2014.9

  The use of 2-halobenzyl tosylates as substrates in copper-catalyzed domino intermolecular substitution/intramolecular arylation processes for the efficient and selective preparation of heterocycles is reported for the first time. Reaction of 2-halobenzyl tosylates with beta-ketoesters delivers 4H-chromenes with yields ranging between 59 and 89%. Imidazobenzothiazines are formed with yields up to 82% upon reaction of 2-halobenzyl tosylates with 2-mercaptoimidazoles. When 2-halobenzyl tosylates are reacted with benzamidines the corresponding quinazolines are obtained. (C) 2014 Elsevier Ltd. All rights reserved.
