Modular synthesis of (C-10 to C-13)-substituted-9,14-diaryl-9,14-dihydrodibenzo[a,c]phenazines via a subsequent Buchwald–Hartwig amination and C–H amination strategy

(C-10 to C-13)-Substituted-9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazines have been synthesized via a cascade Buchwald–Hartwig amination and C–H amination method.
