Abstract

Described herein is an iron(II)-phthalocyanine catalyzed C—H bond amination of alkyl azides. The catalyst is effective to produce intramolecular amination of saturated C—H bonds in moderate to excellent yields and the methods are tolerant of a wide scope of substrates. The methods described are useful for the synthesis of natural products derivatives and for the late-stage functionalization of pharmaceuticals.
