We have developed a convenient and mild catalyst‐free synthesis of structurally diversified indolizinoindoles through [3+2] cycloaddition of dihydro‐β‐carbolines and diarylcyclopropenones. Dimethoxydihydroisoquinolines and 3,4‐dihydrobenzonaphthyridine can also be used in this process affording corresponding polycyclic N‐heterocycles with high molecular complexity.

无催化剂的未活化亚胺与环丙烯酮的[3 + 2]环加成反应

我们通过二氢-β-咔啉和二芳基环丙烯酮的[3 + 2]环加成反应，开发了一种结构轻巧的吲哚并吲哚化合物的便捷且温和的无催化剂合成方法。二甲氧基二氢异喹啉和3,4-二氢苯并萘啶也可用于该过程中，从而提供具有高分子复杂性的相应多环N-杂环。
