Utilization of Donor–Acceptor Interactions for the Catalytic Acceleration of Nucleophilic Additions to Aromatic Carbonyl Compounds

A conceptually new method for the catalytic electrophilic activation of aromatic carbonyl substrates, by utilizing donor–acceptor interactions between an electron-deficient macrocyclic boronic ester host ([2+2]BTH-F) and an aromatic carbonyl guest substrate, was realized. In the presence of a catalytic amount of [2+2]BTH-F, dramatic acceleration of the nucleophilic addition of a ketene silyl acetal towards either electron-rich aromatic aldehydes or ketones was achieved. Several control experiments confirmed that inclusion of the aromatic substrates within [2+2]BTH-F, through efficient donor–acceptor interactions, is essential for the acceleration of the reaction.
