A model reaction of 2-alkyl-3-aminoquinazolones with α-dicarbonyl compounds benzil and its 4, 4′-derivatives, acenaphthenequinone and isatin was studied for the first time. The reaction proceeded in pentafluorophenol and led to the formation of new heterocyclic systems. This approach was used in the synthesis of new thermostable polyheteroarylenes with fluorescent properties, viz., poly(pyridazinoquinazolones).
首次研究了 2-烷基-3-氨基喹唑啉酮与α-二羰基化合物苯偶姻及其 4, 4′-衍生物、苊醌和异atin 的模型反应。反应在五氟苯酚中进行,形成了新的杂环系统。这种方法被用于合成具有荧光特性的新的可恒温聚杂芳基,即聚(哒嗪喹唑酮)。
