Palladium-Catalyzed Desymmetric Intermolecular C–N Coupling Enabled by a Chiral Monophosphine Ligand Derived from Anthracene Photodimer

The development of chiral ligands with privileged scaffolds plays an important role in transition-metal-catalyzed asymmetric reactions. Herein we present anthracene-photodimer-derived chiral monophosphine ligand 1, which features dual chirality and a rigid scaffold. This ligand exhibits remarkable efficiency in Pd-catalyzed desymmetric intermolecular C–N coupling under mild conditions with excellent chemo- and enantioselectivity.
