Palladium-catalyzed allylic substitution reactions have become established as an important tool for the construction of carbon−carbon and carbon−heteroatom bonds in modern organic synthesis. However, controlling the regioselectivity of this type of transformation to afford chiral branched products, in addition to controlling the enantioselectivity, is a significant challenge. Excitingly, controlling nonbonding interactions between the substituents on the π-allyl−palladium intermediate and the nucleophile or palladium catalyst has been shown...
