  A microwave improvement in the synthesis of the quinazoline scaffold

  摘要：

  A rapid and efficient microwave-assisted protocol is described that greatly improves a recent synthetic method developed for quinazoline synthesis. The synthetic protocol is based on the use of cycles of microwave irradiation. The optimization process is reported and the experimental results are compared with those of the conventional synthetic route. (c) 2007 Elsevier Ltd. All rights reserved.

  A new synthetic pathway to quinazolines is described. This new method uses hexamethylenetetramine in TFA and potassium ferricyanide in aqueous ethanolic KOH, starting from simple N-protected anilines. The method affords substituted quinazolines with high selectivities and good yields, reducing reaction-time and work-up operations.

  描述了一种合成喹唑啉的新途径。该新方法从简单的N保护苯胺开始，在TFA中使用六亚甲基四胺，在含水乙醇KOH中使用铁氰化钾。该方法提供了具有高选择性和良好收率的取代的喹唑啉，减少了反应时间和后处理操作。
