Abstract:
The intramolecular halocyclization of alkenes possessing an internal heteroatom nucleophile leads to multifunctional heterocycles which are useful versatile intermediates in organic synthesis. The asymmetric chlorocyclisation of 2-substituted allylic amides gives access to chiral oxazolines bearing a chloromethyl moiety for further synthetic manipulation. The literature reports on this transformation involve complex syntheses of the 2-substituted allylic amides and cryogenic temperatures for achieving high enantioselectivities in the organocatalyzed halocyclization step. Based on the Heck reac

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.1 Introduction2 N-Halo Reagent Mediated Heterocyclic

Abstract:
Halocyclization of alkenes is commonly employed to increase molecular complexity during organic synthesis because it enables double installation of heteroatoms on a carbon–carbon double bond. Moreover, stereodefined halogenated compounds are widely found among naturally occurring compounds and can serve as versatile chiral building blocks. Therefore, the development of asymmetric halocyclization reactions is of great interest and, in recent years, there has been remarkable progress in catalytic asymmetric halogenation reactions.

Abstract:
AbstractA procedure for the preparation of the title salts via regioselective halocyclization of 3-S-propargylthio-4Н-1,2,4-triazoles is reported. Stereoselectivity of electrophilic heterocyclization depends on the nature of the electrophilic reagent: bromination is better than iodobromination and iodination. The heterocyclization with tellurium tetrahalogenides leads to the formation of a mixture of geometric isomers of the salts. Their structure was confirmed by 1H NMR, 13C NMR, НМВС and single crystal X-ray diffraction analysis.
