Abstract

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.
