A one-pot domino C–H, C–C activation in coumarins: a fast track to 2,3-diaryl benzo[b]furans†
Abstract
An approach to synthesize 2,3-diaryl benzo[b]furans using coumarins and aryl bromides is developed. This state-of-the-art strategy capitalizes on a palladium-catalyzed one-pot decarbonylative diarylation of coumarins, paving the way to achieve biologically interesting 2,3-diaryl benzo[b]furans.
