  A four-component procedure for the preparation of substituted quinazolines from anilines, aromatic aldehydes and ammonium iodide is described. The C–H bond ortho to the amino group in anilines was directly functionalized under metal-free conditions. Two aldehydes were involved in this reaction and ammonium iodide was used as one of the nitrogen sources. This reaction provides a strategy for the facile

  An unprecedented Ru(II)-catalyzed C–H activation and annulation reaction, which proceeds via C–C triple bond cleavage, is reported. This reaction of 2-phenyldihydrophthalazinediones with alkynes, which works most efficiently in the presence of bidented ligand 1,3-bis(diphenylphosphino)propane, affords good yields of substituted quinazolines.

  据报道，空前的Ru（II）催化的CH活化和环化反应是通过CC的三键裂解而进行的。2-苯基二氢酞嗪二酮与炔烃的这种反应在双键配体1,3-双（二苯基膦基）丙烷的存在下最有效地进行，产生了高产率的取代喹唑啉。

  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。
