A site-selective bromination of C(sp3)−H bonds in unprotected aliphatic amines has been developed, achieved by tuning of the electronics properties of the proximal C−H bonds via substrate protonation. Consecutive intramolecular cyclization of alkyl bromide offered a series of N-containing heterocycles characterized by high ring strains. Moreover, the resulting C(sp3)−Br serves as a synthetic linchpin
