Iron-Catalyzed Intramolecular C(sp 2)–N Cyclization of 1‑(N‑Arylpyrrol-2-yl)ethanone O‑Acetyl Oximes toward Pyrrolo[1,2‑a]quinoxaline Derivatives

An efficient and convenient iron-catalyzed protocol has been developed for the synthesis of substituted pyrrolo­[1,2-a]­quinoxalines from 1-(N-arylpyrrol-2-yl)­ethanone O-acetyl oximes through N–O bond cleavage and intramolecular directed C–H arylation reactions in acetic acid.
