activity among carbonyl compounds leading to various competitive side reactions. Herein we reported an efficient Pd-catalyzed asymmetric intermolecular α-arylation reaction of α-alkyl-α-aryl disubstituted aldehydes with aryl bromides, which provides a rapid access to chiralaldehydes bearing an α-all-carbon quaternary stereocenter in moderate to good yields with good er in most cases. In addition, a pair
