We have developed a highly enantioselective Pd/chiral acid-catalyzed α-allylation of α-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.

We take advantage of the self-assembly properties of the coat protein of a spherical virus to form uniform tubular nanostructures. Critical to redirecting assembly are the weak interprotein association energy inherent to virus assembly and the relatively rigid nature of the double-stranded DNA scaffold at their core.
