摘要：
Regiodivergent catalysis: Cobalt N-heterocyclic carbene (NHC) catalysts promote intramolecular olefin hydroarylation of indoles bearing an N-homoallyl or bis(homoallyl) tether and a C3 aldimine directing group to afford dihydropyrroloindoles and tetrahydropyridoindoles under mild conditions. The course of the cyclization is dependent on the tether, but can be controlled by the NHC ligand. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
