A novel iron-catalyzed decarboxylative Csp3-Csp2 coupling of proline derivatives and naphthol.

A novel iron-catalyzed intermolecular decarboxylative Csp(3)-Csp(2) coupling reaction using proline derivatives as starting materials is developed. In this process, a series of potentially useful ligands (tertiary aminonaphthol) for catalysis was obtained.
