(HAA) reaction of N-aryl α-amino acids with dienol ethers enabled by a photoredox/palladium dual catalytic system is presented. With the developed method, a broad variety of substrates was deployed to deliver vicinal amino tertiary ethers in good to excellent yields with excellent diastereo-, and enantioselectivity. Mechanistic studies suggest that this transformation proceeds through a reversible
