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