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.

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:
The exploration of chemical space in search of molecules that perturb or mimic biological systems is essential to understanding human biology. The first part of this dissertation (Chapters 1-4) describes efforts to aid in the exploration of biologically relevant space through the invention of new π-cyclization methodologies. This strategy can be viewed as part of a “top-down” approach to investigating biology: the construction of small molecule drugs or probes which modify the behavior of the existing system. The second part of this dissertation (Chapter 5) describes preliminary efforts to exp
