Innovation in synthetic chemistry drives the discovery of new life-saving drugs, agrochemicals and functional materials. This project aims to use visible light to access underexploited reactive intermediates and harness their unique reactivity in new sustainable synthetic transformations. The new chemical processes are expected to deliver increased economy, efficiency and precision in the synthesis of bioactive molecules that are inaccessible or challenging to prepare with existing technologies. The conceptual and practical outcomes of this project are expected to benefit both academia and industry as the use of hazardous and expensive metal catalysts can be avoided, reducing chemical waste and simplifying purification.Read moreRead less
Enhanced Synthetic Efficiency For Molecular Complexity and Diversity. This project aims to introduce new, broad-spectrum strategies that permit more efficient and selective ways to access complex organic molecules. The approach involves maximising the molecule-building potential of some of the smallest accessible molecular building blocks.

Multi-Bond-Forming Processes: Step-Economical Synthesis In Batch And Flow. This project aims to develop better ways to make and understand organic substances: the materials that make up all known life forms, our medicines, and many designed materials. Based on the previous development of powerful multi-bond-forming processes, the purpose of this project is to develop cascade sequences involving dendralenes in new and innovative ways.

This project aims to develop better ways to make and understand organic substances: the materials that make up all known life forms, our medicines, and many designed materials. Based on the previous development of powerful multi-bond-forming processes, the purpose of this project is to develop cascade sequences involving dendralenes in new and innovative ways. The project plans to generalise these processes and apply them in short total syntheses; extend the boundaries of multi-bond-forming processes and break new records; and reach higher levels of synthetic efficiency and selectivity by introducing the latest flow chemistry and automated reaction optimisation technology.Read moreRead less
Organic Linchpin Reagents to Construct Structural Diversity and Complexity. High-energy chemical species such as carbenes, nitrenes or free radicals are often used as reactive intermediates in organic reactions to rapidly generate new bonds, structures and structural complexities. Due to their reactive nature, traditionally only one type of high-energy chemical species can be featured at a time to avoid unwanted complicated side reactions. This project aims to develop novel synthetic substrates ....Organic Linchpin Reagents to Construct Structural Diversity and Complexity. High-energy chemical species such as carbenes, nitrenes or free radicals are often used as reactive intermediates in organic reactions to rapidly generate new bonds, structures and structural complexities. Due to their reactive nature, traditionally only one type of high-energy chemical species can be featured at a time to avoid unwanted complicated side reactions. This project aims to develop novel synthetic substrates bearing multiple carbene and nitrene precursors of different types. These high-energy intermediates can be released in a relayed fashion by controlling orthogonal stimuli and therefore acting as linchpin reagents for quick construction of bio- or photo-active compounds and unprecedented complicated structures.Read moreRead less

This project aims to mimic the way in which Nature constructs organic compounds and thus develop more efficient, greener synthetic processes in which there is a rapid build up of molecular complexity via “biomimetic” reactions. We will integrate this approach with modern methods of catalysis, including electrochemistry, photochemistry and biocatalysis. As a result, this work will expand the chemical space available to synthetic chemists working in the pharmaceutical industry.

Polarity inversion of conjugate acceptors: New opportunities in catalysis. Conjugate acceptors are common chemicals that are readily available from petrochemical and biomass feedstocks. While they are used extensively to build functional materials, including polymers and medicines, the reactions that they can engage in are largely limited to those exploiting their natural reactivity. In this project, catalysis will be used to allow these ubiquitous building blocks to react in entirely new ways. ....Polarity inversion of conjugate acceptors: New opportunities in catalysis.
