Profile

Alison Stuart is a synthetic organic chemist who specialises in the production of fluorine-containing organic molecules and has >60 publications in organofluorine chemistry. She recently developed a new fluorinating reagent, Fluoroiodane, and used it to produce novel fluorinated heterocycles. She is the leader of the Sustainable Synthesis and Catalysis Research group in the School of Chemistry.

Research

My research is focussed on designing new synthetic methodology for introducing fluorine into organic molecules because of the importance of incorporating fluorine into drug candidate molecules. Over the last 60 years fluorinated molecules have proved crucial in the development of new pharmaceuticals and there are approximately 200 pharmaceuticals that contain fluorine. Consequently the chemical industry still needs more efficient, safer and cheaper methods for fluorination. In 2013 we prepared the fluoroiodane reagent and demonstrated its application as a new fluorinating reagent with 1,3-dicarbonyl substrates.[7] Since then, the reaction scope of fluoroiodane has extended significantly, but most of these reactions required a transition metal catalyst to activate the fluoroiodane reagent. We discovered that fluoroiodane can be activated by hydrogen bonding to hexafluoroisopropanol removing the need for transition metals.[3] A major advantage of using fluoroiodane is that it offers different regioselectivity in fluorocyclisations compared to traditional electrophilic fluorinating reagents (e.g. Selectfluor) and it provides access to novel fluorinated heterocycles.[1,4]
