Rhodium-catalyzed alkyne hydroacylation using alkyl β-S-aldehydes, enantioselective rhodium-catalyzed aryl boronic acid conjugateaddition, and sulfide elimination are combined in sequence to provide β′-aryl enones. The reaction sequence is efficient and delivers highly functionalized products with excellent levels of enantiocontrol. Good variation of the three reaction components is demonstrated.
