We report here an unprecedented and highly enantioselective palladium‐catalyzed allylic alkylation applied to 4‐substituted isoxazolidin‐5‐ones. Ultimately, the process provides a straightforward access to β2,2‐amino acids bearing an all‐carbon quaternary stereogenic center in great yields and a high degree of enantioselectivity.
