An efficient route has been developed for the facile synthesis of functionalized 2-arylpiperidines that may be readily modified using straightforward transformations to create collections of novel substituted 2-arylpiperidines. The approach features a reaction cascade starting with imine formation from a known amino allylsilane and a diverse set of aryl aldehydes, followed by an acid-catalyzed aza-Sakurai
已经开发出一种有效的途径来容易地合成官能化的2-芳基哌啶,该官能化的2-芳基哌啶可以使用简单的转化容易地修饰以产生新的取代的2-芳基哌啶的集合。该方法的特征在于反应级联反应,该反应级联反应是从已知的氨基烯丙基硅烷和各种不同的芳基醛形成亚胺,然后进行酸催化的aza-Sakurai反应,以在单个反应中组装一系列2-芳基-4-外-亚甲基哌啶从容易获得的起始原料开始。通过N-甲基化,N-乙酰化和N-甲苯磺酸化使如此制备的2-芳基-4-外-亚甲基哌啶衍生化。
