Abstract 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.
