New Discoveries in Organic Synthesis Inspired by the Efficiency of Nature. Nature can assemble complex organic molecules from simple starting materials with apparent ease, but the laboratory synthesis of these natural products is very difficult. 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.

Nature can assemble complex organic molecules from simple starting materials with apparent ease, but the laboratory synthesis of these natural products is very difficult. 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. A further benefit is the training of the next generation of Australian synthetic chemists. Read moreRead less

Metal-organic Framework (MOF) Superstructure Catalysts. The development of new catalyst technology is crucial to uncovering energy-efficient strategies for valorising chemicals. Although the designable pore networks of Metal-organic Frameworks (MOFs) provide a highly favourable environment for heterogeneous catalysis, most stable MOF materials are microporous - possessing pores less than 2 nm - which hinders mass transport.

The development of new catalyst technology is crucial to uncovering energy-efficient strategies for valorising chemicals. Although the designable pore networks of Metal-organic Frameworks (MOFs) provide a highly favourable environment for heterogeneous catalysis, most stable MOF materials are microporous - possessing pores less than 2 nm - which hinders mass transport. This research will develop novel, hierarchically porous MOF superstructures that will overcome these limitations and serve as platform materials for the development of new catalysts. This research will address future challenges in industrial catalysis and realise an important step towards the commercial application of MOF catalysis for valoriation of chemical feedstocks.

This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in situ. This will enable the control of stereochemistry in photoredox reactions – not possible with standard catalysts - and establish other useful synthetic transformations. These strategies will make it easier to prepare valuable classes of organic molecules – efficiently, safely, and cost-effectively.
