Abstract

A Pd-catalyzed intermolecular 1,2-carboamination route to indolines from N-aryl ureas and 1,3-dienes proceeds under mild conditions in relatively nonacidic media via a C-H insertion/carbopalladation/nucleophilic displacement process. The in situ generation, or preformation of a palladium tosylate emerges as a key parameter in gaining the requisite reactivity.
