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
