A method for the CuFe2O4-catalyzed coupling of 2-iodo- or 2-bromoanilines and acetylacetone or isosteric 1,3-diketones to afford 2,3-disubstituted indoles has been developed. The superparamagnetic material showed superior activity in comparison to other ferrites or copper-based metal–organic frameworks. Functionalities including ester, cyano, and halogen groups were compatible with the reaction conditions. The CuFe2O4 catalyst was easily recoverable and reusable and offers a convenient pathway to afford synthetically useful heterocycles.

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. Copyright
