Development of copper-catalyzed enantioselective alkene difunctionalization reactions via radical intermediates
… efficient oxytrifluoromethylation of unactivated alkenes based on a copper-catalyzed ligand-assisted difunctionalization strategy has been developed. This method provides access to a variety of classes of synthetically useful CF3-containing building blocks from simple starting materials. Chapter 2 …

Rhodium-Catalyzed Enantioselective Desymmetrizations of Oxabicyclic Alkenes and Alkene Difunctionalization via Nickel-Catalyzed Arylcyanation
… cycloisomerization reaction of oxabicyclic alkenes. Our work on developing the intramolecular asymmetric ring opening reaction led to the discovery of a novel epoxide synthesis. Specifically, when bridgehead substituted oxabicyclic alkenes with non-nucleophilic side chains are reacted with …

Stereoselective Heterocycle Synthesis via Alkene Difunctionalization: Bulky Phosphine Ligands Enable Pd-Catalyzed Arylhalogenation, Arylcyanation and Diarylation
… different classes of heterocycles using the alkene aryliodination methodology: isochromans, chromans, and dihydroisoquinolinones. The use of amine bases was found to be key in these transformations. The dihydroisoquinoline synthesis was employed as the key carbon–carbon bond forming step in …

Chloro-arylation of Alkenes via Cooperative Photoredox and Atom-transfer Catalysis
… radical mediated chloro-arylation reaction of alkenes. The goal was to obtain alkyl chlorides with high structural diversity from readily available alkenes and diaryliodonium salts. The developed transformation benefits from a high degree of modularity through the independent functionalization …

Development of three-component alkene and 1,3-diene carbofunctionalization reactions
… demands, we have developed a three-component alkene carboamination reaction. This system offers access to complex amine products from simple starting materials and proceeds under mild reaction conditions. Critically, this transformation combines disconnected carbon, nitrogen, and alkene …

Organoselenium redox-catalyzed, enantioselective syn-difunctionalization of alkenes
… and -catalyzed reactions of alkenes, as distinguished from other modes of organoselenium reactivity (e.g. Lewis base and peroxoselenenic acid reagents). Special attention is paid to the wealth of diastereoselective selenofunctionalization reactions with chiral, enantioenriched …

A Radical Approach to Photochemical Transformations Using Earth-Abundant Metals
… and natural product syntheses. Radical difunctionalization is a powerful reaction scheme to incorporate useful functionalities onto unsaturated hydrocarbons, especially the prevalent unactivated alkene class. While atom transfer radical addition (ATRA) has been adopted in …
