title: Rhodium(III)-catalyzed direct oxidative cross coupling at the C5 position of chromones with alkenes.
abstract: An atom-economical, Rh(III)-catalyzed, direct oxidative cross-coupling at the C5 position of chromones and flavones with a broad range of alkenes was developed. The products were formed in a highly regioselective manner in good to excellent yields. The developed method was applied in the cross-coupling of natural products for the synthesis of hybrid molecules.
