    摘要:
    (芳基亚氨基)二氮丙啶在 60-100 °C 的温度下在几个级联反应中重排。那些拥有未占据的邻位产生荧光的 3-氨基-2H-吲唑和 2-氨基-1H-苯并咪唑。如果两个邻位都被甲基封闭,则不会形成吲唑而形成深黄色的 2-imino-2,3-dihydro-3aH-苯​​并咪唑,其通过 Diels-Alder 反应部分二聚或通过形式损失再生芳香体系通道 2。此外,2,6-二甲基苯环的甲基之一参与 [1,7] H 位移,提供邻醌中间体,该中间体经过 1,6-电环化以提供 2-氨基-3,4-二氢喹唑啉。五元环杂环的形成被解释为通过 [1,3] N 位移的价异构化来产生难以捉摸的 1-芳基-3-亚氨基二氮丙啶作为第一步。它们立即经历三氮杂-Cope 重排为苯并咪唑衍生物或 NC 键的电环打开以生成共轭偶氮甲亚胺(1,5-偶极子),然后它们的 1,5-电环化为吲唑。(芳基亚氨基)二氮丙啶衰变的一级速率常数将

    or regenerate the aromatic system by formal loss of CH 2 . In addition, one of the methyl groups of 2,6-dimethylphenyl rings is involved in a [1,7] H shift affording orthoquinonoid intermediates which undergo 1,6-electrocyclization to furnish 2-amino-3,4-dihydroquinazolines. The formation of five-membered ring heterocycles is interpreted in terms of valence isomerization by [1,3] N shift to yield elusive
