(A) Aminoarylation with (Z)-anethole (28). (B) Tracking reaction progress for aminoarylation with (Z)-anethole (28) (▲ = 2, ■ = (Z)-anethole, ♦ = 9, ■ = (E)-anethole). (C) Determination of the photostationary state for anethole isomers catalyzed by 3. (D) Favored and disfavored conformations for intermediate III.
