herein is the first example of 2‐allylazaarenes in asymmetric catalysis. Highly γ‐selective allylation was demonstrated for activated ketones, including isatins and trifluoromethyl ketones. In the presence of either an amino‐acid‐based tertiary amine or quaternary ammonium salt catalyst, two series of tertiary hydroxy‐containing moieties were installed at the remote δ‐position of azaarenes in good chemical
