use of allylic amines as allylating agents in the chiral α-aminoacid/palladium-catalyzed asymmetric allylation of α-branched β-ketoesters, providing highly enantioselective access to all-carbon quaternary stereocenters. Notably, the formation of a primary amine, a secondary amine, or ammonia as a byproduct has little influence on the enantioselectivity for the catalytic asymmetric synthesis of structurally
