Abstract
Heterocyclic chemistry is an essential frontier in science and a source of novel biologically
active compounds. The development of innovative synthetic methodologies that allows
access to different heterocyclic rings is of critical interest to the scientific community.
This review will focus on recent applications of N -halo compounds (e.g., N -halosuccinimides, trihaloisocyanuric acids, N -halosulfonamides, etc.) in heterocyclic construction via electrophilic cyclization,
asymmetric halocyclization, oxidative cyclization, and radical processes.
