  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。

• Base-promoted N-alkylation using formamides as the N-sources in neat water
  作者：Wen-Xin Chen、Cai-Yun Zhang、Li-Xiong Shao

  DOI：10.1016/j.tet.2013.12.031

  日期：2014.1

  An efficient catalyst-free, alternative method for the C-N bond formation reaction of alkyl electrophiles using formamides as the N-sources was achieved under mild conditions. The reaction possesses the advantages of a broad range of substrates scope and wide functional group tolerance. It should also be noted that this process was performed using the environmentally benign water as the sole solvent, and high yield can also be achieved in ten-gram scale. (C) 2013 Elsevier Ltd.
