cross-coupling of bromo(iso)quinoline to 1,6-diynes with the Pd-catalyzed system was established. Using unactivated simple diynes with bromo(iso)quinoline in the presence of palladium catalytic system afforded different kinds of rare 7,11-diphenyl-9,10-dihydro-8H-pyrrolo[3,4-j]phenanthridine derivatives through regioselective C–H functionalization in one step. Different diynes (a–p) and different bromo(iso)quinolines
