Multiple displacement of oxygen: Electron‐rich oligopyrroles and pyrrolo[3,2‐e]indoles are generated by a domino process induced by donor–acceptor‐substituted cyclopropanes. Up to seven molecules of water are eliminated, thus allowing the introduction of nitrogen and aromaticity.
氧气的多次置换:富电子的低吡咯和吡咯并[3,2- e ]吲哚是由供体-受体取代的环丙烷诱导的多米诺过程生成的。消除了多达七个分子的水,从而引入了氮和芳香性。
