Abstract:

Magnetite nanoparticles coated with sulfuric acid-functionalized mesoporous MCM-48 were synthesized and used as a catalyst in three-component domino reactions of indoles, arylglyoxal monohydrates and N-arylenaminones to furnish the desired 3,3'-bisindoles by formation of two C-C and one C-N bonds in a smooth cascade with good yields under mild reaction conditions. The catalyst was recovered easily and maintained activity in successive runs.

Key words: Fe3O4, Mesoporous, Nanoparticle, Core-shell, 3,3'-Bisindole
