Herein, we report a rare pentacyclic N ‐fused hetrocycle synthesis via palladium catalyzed intramolecular C−H arylation along with the brief synthetic study of new type of bicyclic/tricyclic pyrrole rings. This pyrrole rings provided diversely substituted polycyclic nitrogen fused heterocycles from N ‐benzyl/ N ‐benzyloxy pyrroles with good to excellent yields.
