Abstract (Summary)

Nitrogen heterocycles are ubiquitous in bioactive compounds. The development of new chemical methods which provide an efficient and concise synthesis of these molecules is a prevalent topic. The research described herein examines the formation of nitrogen heterocycles utilizing copper(II)-catalyzed difunctionalization reactions of alkenes. In Chapter I, a copper-catalyzed enantioselective intra/intermolecular alkene diamination is described. This reaction couples various γ-alkenyl sulfonamides with various external sulfonamides via a tandem cyclization/coupling sequence and enables formation of chiral 2-methylamino indolines and pyrrolidines. Chapter II is focused on the copper-catalyzed enantioselective diamination/cyclization of N-sulfonyl-2-allylanilines to synthesize chiral 2-methylindolines. The method was expanded to include various substitutions on the aniline ring of the substrate, and provided hydroamination products with up to 90% ee.
