of the notorious aryls is solved: The first efficient catalytic and enantioselective method for allylicsubstitutions that furnish quaternary carbon stereogenic centers by additions of aryl‐ or heteroarylmetals is reported (see scheme). Highly site‐ and enantioselective processes begin with readily available organolithium reagents.
