A simple method for the synthesis of pyrrolo[2,3-c]carbazoles from N-alkylated-3-aminocarbazole derivatives and ethylene glycol has been developed via heteroannulation reaction using RuCl3/SnCl2 system. Moreover indolo[2,3-c]carbazoles were prepared from various pyrrolo[2,3-c]carbazoles in good yields.
通过RuCl 3 / SnCl 2体系的杂环化反应,开发了一种由N-烷基化-3-氨基咔唑衍生物和乙二醇合成吡咯并[2,3- c ]咔唑的简单方法。此外,由各种吡咯并[2,3- c ]咔唑制备了吲哚[2,3- c ]咔唑,收率很高。
