We have developed a highly enantioselective Pd/chiral acid-catalyzed alpha-allylation of alpha-branched aldehydes with an allyl amine as the allylating species that creates all-carbon quaternary stereogenic centers in high yields and enantioselectivities. To our knowledge, this is the first time that a chiral anionic ligand is applied for achieving asymmetric induction in a palladium-catalyzed allylic alkylation reaction.
