The first two highly enantioselective palladium‐catalyzed allylic alkylations with benzylic nucleophiles, activated with Cr(CO)3, have been developed. These methods enable the enantioselective synthesis of α‐2‐propenyl benzyl motifs, which are important scaffolds in natural products and pharmaceuticals. A variety of cyclic and acyclic allylic carbonates are competent electrophilic partners furnishing
