Ir-Catalyzed C-H Amidation and Borylation of Anthraquinones

摘要

A mild, regioselective, iridium-catalyzed C-H amidation and borylation of anthraquinones to the o-sulfonamide and m-borylated products has been developed. The anthraquinone carbonyl moieties direct the C-H amidation with high selectivity to afford the ortho-substituted products in modest to high yields.
