Copper-Catalyzed Four-Component Borocarbonylative Allylation of Vinyl Arenes to β-Boryl Enones

Abstract

We present here a novel copper-catalyzed four-component borocarbonylative allylation of aryl olefins. Utilizing carbon monoxide as the carbonyl source under mild reaction conditions, this protocol employs readily available aryl olefins, bis(pinacolato)diboron, and allylic phosphates as the substrates to enable the simultaneous introduction of boron, carbonyl, and allyl groups.
