An asymmetric Ni-catalyzed intramolecular reductiveHeckreaction of unactivated alkenes tethered to aryl bromides has been accomplished, providing a variety of benzene-fused cyclic compounds bearing a quaternary stereogenic center in good to excellent yields and high enantioselectivities. A mechanism has been proposed, which involves the enantiodetermining migratory insertion and the following protonation

Reported is an asymmetric reductive dicarbofunctionalization of unactivatedalkenes. Under the catalysis of a Ni/BOX system, various aryl bromides, incorporating a pendant olefinic unit, were successfully reacted with an array of primary alkyl bromides in the presence of Zn as a reductant, furnishing a series of benzene‐fused cyclic compounds bearing a quaternary stereocenter in high enantioselectivities
