  路线到高度取代的吡啶

  摘要：

  吡啶环是在许多生物活性化合物（包括一些畅销药物）中发现的常见结构基序。我们已经开发出一种新的方法来获得取代的吡啶。该方法旨在通过三步法提供可靠的合成范围广泛的取代吡啶。易于获得的烯酮首先通过两步Hosomi-Sakurai烯丙基化/氧化裂解序列转化为1,5-二羰基，然后使用盐酸羟胺将其环化为相应的吡啶。使用该方法已经合成了多种取代的吡啶。

• An Unexpected Diethyl Azodicarboxylate-Promoted Dehydrogenation of Tertiaryamine and Tandem Reaction with Sulfonyl Azide
  作者：Xiaoliang Xu、Xiaonian Li、Lei Ma、Ning Ye、Bojie Weng

  日期：2008.10.29

  It is shown here for the first time that diethyl azodicarboxylate promotes dehydrogenation of tertiaryamines to afford enamines, which subsequently take place in tandem reactions with sulfonyl azides to give the N-sulfonyl amidine derivatives. A number of different substituted tertiaryamines and sulfonyl azides can successfully be coupled, and several functionalized groups are tolerated in this system. The reaction described here is mild, general, and efficient, thus providing an extremely preferable method for synthesis of a variety of N-sulfonyl amidine derivatives.
