Abstract Novel aryl and alkenyl aluminum reagents are generated through a halogen/Li exchange-Li/Al transmetalation sequence. These aryl alanes are used in the copper-catalyzed asymmetric conjugate addition reaction to a variety of cyclic enones giving chiral aryl-substituted quaternary centers. Both, electron-donating and electron-withdrawing groups give full conversion and very good ee values.
