One-pot Synthesis of Indolino[2′,3′:1,2][60]fullerenes from Fullerene Epoxide: Lewis Acid-assisted Nucleophilic Addition Followed by Intramolecular Cyclization

An efficient one-pot method for the synthesis of indolino[2′,3′:1,2][60]fullerene derivatives was developed, in which the formation and cyclization of a β-amino alcohol intermediate by the nucleophilic reaction of fullerene epoxide with aromatic amines was promoted in the presence of aprotic heterogeneous catalysts.
