文摘

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.
