A general, highly selective asymmetric redox-relay oxidative Heck reaction using achiral or racemic acyclic alkenols and boronic acids delivers remotely functionalized arylated carbonyl products, with excellent enantioselectivity under mild conditions, bearing a range of useful functionality. The regioselectivity of the initial migratory insertion depends on the electronic nature of the boronic acid.
