A highly efficient Pd-catalyzed allylic alkylation reaction of azlactones with vinyl aziridine has been achieved for the first time to access functionalized quaternary allylic amino acid derivatives (17 examples, up to 89% yield and 80% ee). Moreover, the broad scope and easy transformations of the products reinforce the value of this approach, which can enrich the chemistry of quaternary allylic amino acid derivatives.
