Abstract
An asymmetric Ni-catalyzed intramolecular reductive Heck reaction of unactivated alkenes tethered to aryl bromides provides various benzene-fused cyclic compounds bearing a quaternary stereogenic center in good to excellent yields and high enantioselectivities. A mechanism involves an enantiodetermining migratory insertion and a subsequent protonation with water or alcoholic solvents.
