Asymmetric allylation reactions have turned out to be extremely useful in the creation of molecular complexity.[1-2] Both the Pd-catalyzed asymmetric allylic alkylation[1] and allylation of carbonyls[2] have been well investigated.However,activated precursors of π-allyl fragments,including allylic halides,esters,carbonates,and even allylic alcohols have dominantly been employed in these transformations.In contrast,the asymmetric allylation reactions based on allylic C-H activation have much less been reported.Recently,the metal/organo combined catalysis has been a general concept for creation of new transformations and shown the unique robustness to enable asymmetric functionalization of relatively inactive bonds.[3] At this symposium,we will describe the C-H activation-based asymmetric allylic alkylation[4-5] and allylation of carbonyl compounds[6] under the cooperative catalysis of palladium complexes and Bronsted acids.
