Rhenium‐ and Aniline‐Catalyzed One‐Pot Annulation of Aromatic Ketones and α,β‐Unsaturated Esters Initiated by CH Bond Activation

Several reaction steps, including CH activation, lead to indene derivatives in good yields in the rhenium-catalyzed reaction of aromatic ketimines and ethyl acrylate. Indene derivatives can also be obtained by the reactions of aromatic ketones with α,β-unsaturated esters in the presence of a catalytic rhenium complex and p-anisidine (see scheme).
