The first cascade diastereoselective synthesis of oxazoloisoindolinones via the palladium-catalyzed decarboxylative ortho-acylation of N-benzoyl α-aminoacid derivatives followed by double intramolecular cyclizations has been demonstrated. This reaction, using α-aminoacids as directing groups and α-oxocarboxylic acids as the acylation source, features a broad substrate scope, good functional group

Brønsted Acid Accelerated Pd-Catalyzed Direct Asymmetric Allylic Alkylation of Azlactones with Simple Allylic Alcohols: A Practical Access to Quaternary Allylic Amino Acid Derivatives
A Brønsted acid accelerated Pd-catalyzed asymmetric allylicalkylation of azlactones with simple allylicalcohols under mild reaction conditions has been realized, which provides a direct and readily scalable approach for the synthesis of all-carbon quaternary allylic amino acid derivatives in excellent yields and good enantioselectivities.
