Acyclicquaternarycarbons by conjugateaddition: The first examples of catalytic enantioselectiveconjugateadditions of aryl and alkyl units that generate acyclic all‐carbonquaternarystereogeniccenters have been developed (see scheme). The requisite organoaluminum reagents can either be prepared in situ from easily available organolithiums or purchased at low cost.
