A straightforward single step method for the preparation and/or production of substituted quinazolines is disclosed, wherein said quinazolines preferably contain one substituent at position 4, and may contain other functional groups at various positions, such as 5, 6, 7, and/or 8 of quinazolines. In addition, the extension of this new method leads to the formation of different type of heterocyclic aromatic compounds, that include but are not limited to perimidines, anthrapyrimidin-7-ones (also known as anthrapyrimidinones), anthra[1,9:5,10]dipyrimidines (also known as quinazoline[5,4-ef]perimidines) and benzo[e]-pyrimido[4,5,6-gh]pyrimidines.
本发明揭示了一种制备和/或生产取代喹唑啉的简单单步方法,其中所述喹唑啉优选在位置4处含有一个取代基,并且可能在喹唑啉的各种位置,例如5、6、7和/或8处含有其他官能团。此外,这种新方法的扩展还导致不同类型的杂环芳香化合物的形成,包括但不限于咪唑啉、蒽吡咯啉-7-酮(也称为蒽吡咯啉酮)、蒽[1,9:5,10]二咪唑啉(也称为喹唑啉[5,4-ef]咪唑啉)和苯并[e]-嘧啶[4,5,6-gh]嘧啶。
