About the Project
Background: The application of radical chemistry in synthesis has recently undergone a renaissance due to their powerful translational potential. Nevertheless, the generation of radicals is often associated with toxic, non-sustainable/expensive metals, photocatalysis, light, high temperatures or electrochemistry. This proposal builds on surprising observations in our lab that, contrary to the accepted convention, mild, decarboxylative C-H functionalisation of heterocycles does not require metal, photocatalyst, light, high temperatures nor electrolysis to proceed well.[2,3] A simple switch of solvent, followed by optimisation, successfully renders the C-H functionalisation of heterocycles metal-, catalyst-, light- and electrolysis-free! These sustainable and scalable conditions constitute a significant advance on cost, toxicity, waste and simplicity of operational procedure.
PhD Project: Following these exciting preliminary results, the aim of this collaborative PhD project is to extend our sustainable methodology to develop scalable, late-stage C-H functionalisations of pharmaceutically relevant heterocycles. In our proof-of-principle work, we predominantly based our optimisation studies on isoquinolines. In this PhD project, we will investigate the C H functionalisations of important classes of pharmaceutically relevant heterocycles, which were not the focus of our proof-of-principle study. Full optimisation and substrate scope studies will be carried out on the alkylation, acylation as well as carbamoylation reactions, and gram-scale reactions as well as late-stage C-H functionalisations will also be demonstrated to showcase the scalability and functional group tolerance.
