A protocol on chemoselective cobalt(II) porphyrin‐catalyzed intramolecular cyclopropanation of N‐alkyl indoles/pyrroles with alkylcarbenes has been developed. The reaction enables the rapid construction of a range of nitrogen‐containing polycyclic compounds in moderate to high yields from readily accessible materials. These N‐containing polycyclic compounds can be converted into a variety of N‐heterocycles
