关于我们一般合成多环杂芳族化合物的机理方面的研究表明,遵循方案2中概述的反应序列。在我们的合成条件下,邻位重排(8)→(9)优于已知在酸性条件下发生的对位重排。在分子间反应中,苯胺曼尼希碱(29)被转化为苯并[ a ] r啶(30)。合成似乎仅限于推定的中间体(9)不属于酰胺基团的底物。在这些研究过程中,已经发现了三环化合物(24)和(25)的有效合成。

A general and straightforward new synthesis of polycyclic heteroaromatic compounds has been developed. In the synthesis a putative quinolone-quinone-methide is generated in the presence of an aniline. The ensuing reaction results in a polycyclic heteroaromatic product. In the most useful approach, a hemiacetal (25) is prepared in one step from the parent quinolone and this is heated in the presence
