A convergent strategy is reported for the construction of nitrogen-containing heterocycles from common substrates: 1,4-diketones and primary amines. Indeed, by just varying the substrates, the substituents, or the heating mode, it is possible to selectively synthesize indole, indolone (1,5,6,7-tetrahydroindol-4-one), or cinnoline (5,6,7,8-tetrahydrocinnoline) derivatives in moderate to excellent yields.

从常见的 1,4-二酮迈克尔受体可调节地获取吲哚、吲哚酮和肉桂啉衍生物。


据报道，从共同底物：1,4-二酮和伯胺构建含氮杂环的收敛策略。事实上，仅通过改变底物、取代基或加热模式，就可以选择性合成吲哚、吲哚酮（1,5,6,7-四氢吲哚-4-酮）或肉啉（5,6,7, 8-四氢肉啉）衍生物，产率中等至优异。
