  对多环喹唑啉酮，苯并恶嗪酮和苯并噻嗪酮的三组分反应

  摘要：

  在新的三组分一锅法反应中，实现了易于参与的环状亚胺与酰基氯的有效转化，该亚胺能够参与亲核芳香族取代（S N Ar）反应，至少产生三环环化喹唑啉酮，苯并恶嗪酮分别是由于使用了氮，氧或硫亲核试剂而产生的苯并噻嗪酮。特别是在喹唑啉酮的情况下，这种方便的策略使人们能够进入多样性更高的杂环，这为精细杂环骨架的有效衍生化提供了发展。在随后的Heck或Ullmann环化中，可以对所提及的喹唑啉酮进行进一步的环合。

  日期：——

  A new synthetic sequence including two sequential multicomponent reactions leading to a wide range of thiazolo-and oxazolo-annulated benzodiazepinediones is described. This strategy features simple one-pot operations under mild conditions in combination with a high degree of diversity, and can be realized based on commercially available or easily accessible starting materials.
• Synthesis of different types of valerolactams starting from 2,5-dihydrooxazoles
  作者：Katharina Johannes、Jürgen Martens

  DOI：10.1016/j.tet.2009.10.107

  日期：2010.1

  Tricyclic valerolactams characterized by a variable heteroatom in gamma-position, for example, sulfur, oxygen or nitrogen, were synthesized starting from 2,5-dihydrooxazoles. The chosen synthetic procedures included the addition of thiosalicylic acid as well as the addition of salicyl chloride. The nitrogen containing lactams were prepared in a cycloaddition and subsequent oxidation. (C) 2009 Elsevier Ltd. All rights reserved.
