Investigations of Catalysts Which Utilise Non-Covalent Interactions to Control Enantioselectivity in Rhodium-Catalysed Amination of C(sp3)–H Bonds
Investigations into enantioselective benzylic C(sp3)–H amination via bis-sulfonated rhodium(II) dimers ion-paired with N-quaternised Cinchona alkaloids are described herein. Design and initial synthesis of these novel catalysts was performed prior by Dr. Alex Fanourakis, and their application …

New Catalysts for Asymmetric Nitrene Transfer Based on Ion-Pairing Between Sulfonated Rhodium(II,II) Tetracarboxylates and Chiral Cations: Design, Synthesis and Applications to Enantioselective Carbon-Nitrogen Bond Formation
… for the catalytic, asymmetric synthesis of C(sp3)–N bonds and is divided into three parts. First, the design and synthesis of a novel class of chiral rhodium(II,II) tetracarboxylate dimer is presented. Inspired by a design strategy previously developed within the Phipps research group for …

C(sp3)-H aminations under first row transition metal catalysis
… to introduce nitrogen (e.g. Mannich, reductive amination) often rely on pre-existing functionality and require additional transformations such as oxidation state changes and/or protecting group maniuplations. C—H amination represents a powerful alternative synthetic strategy. This approach …
