Direct dearomative C3-functionalization of indoles provided access to privileged scaffolds by an umpolung strategy. Against all odds, C3-indolium intermediates could be generated from NH-indoles under operationally simple conditions with triflic acid at room temperature to promote intra- and intermolecular C3-regioselective hydroarylation. DFT studies suggest that these cationic or dicationic intermediates

Dearomatization of an indole via palladium(0)-catalyzed cross-coupling reaction has been realized. With readily available triphenylphosphine as ligand, various spiroindolenine derivatives have been obtained in good to excellent yields, and enantioselective control is also feasible with chiral ligands.
