N-C axially chiral phenanthridin-6-one derivatives bearing various ortho-substituted phenyl groups on the nitrogen atom were enantioselectively prepared through (R)-DTBM-SEGPHOS-Pd(OAc)2-catalyzed intramolecular Buchwald-Hartwig amination. The enantioselectivity strongly depended on solvents, bases, and reaction temperature as well as on the bulkiness of ortho-substituents.
