Synthesis of carbazol-4-ones, 3,4-dihydrocyclopental-indol-1-one, and indole derivatives by a Fe/AcOH-mediated intramolecular reductive N-heteroannulation of 3-hydroxy-2-(2-nitrophenyl)enones is demonstrated. The same protocol has been extended to access indolocarbazolone and indoloquinolone derivatives. Synthesis ofderivatives by a Fe/AcOH-mediated intramolecular reductive N-heteroannulation strategy is demonstrated. The starting materials were easily accessed from C-arylation of 1,3-diketones by o-nitroiodobenzenes.
