primary aliphatic and aromatic amines, 1,2‐phenylenediamine, hydrazine hydrate, and formamide, have been investigated and afford the corresponding quinazolinones which are expected to have some interesting biological activity. The behavior of 3, 1‐benzoxazin‐4‐one toward active methylene compounds, namely, acetylacetone in basic medium has been studied and gave 3‐acetylquinoline. The last reaction is considered
6-溴-2-异丙基-4(3H)-3,1-苯并恶嗪-4-酮与单和二齿氮亲核试剂的反应,例如脂肪族和芳香族伯胺,1,2-苯二胺,水合肼,已经研究了甲酰胺和甲酰胺,并提供了相应的喹唑啉酮,预期它们具有一些有趣的生物学活性。研究了3,1-苯并恶嗪-4-酮在碱性介质中对活性亚甲基化合物即乙酰丙酮的行为,并得到了3-乙酰喹啉。最后的反应被认为是杂环转化反应的说明性模型。
