New antiparasitics to protect Australian livestock. There is an urgent need for new antiparasitics to treat multi-drug resistant livestock infections. This project aims to explore the bacteria and fungi present in the microbiomes of heavily infected sheep faeces and pastures, challenging them with environmental cues, including those from associated parasites, to stimulate production of defensive chemicals hidden deep within their genomes. Enabled by an integrated pipeline of high throughput anal ....New antiparasitics to protect Australian livestock. There is an urgent need for new antiparasitics to treat multi-drug resistant livestock infections. This project aims to explore the bacteria and fungi present in the microbiomes of heavily infected sheep faeces and pastures, challenging them with environmental cues, including those from associated parasites, to stimulate production of defensive chemicals hidden deep within their genomes. Enabled by an integrated pipeline of high throughput analytical cultivation, molecular networking, and chemical and biological analyses, expected outcomes include an enhanced ability to explore and exploit valuable chemistry hidden within microbial genomes, leading to the discovery of new classes of natural antiparasitic to safeguard livestock.

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. We will integrate this app ....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. 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
Biomimetic Synthesis of Dimeric Natural Products. The aim of this research is to use nature as a source of inspiration and direction to improve and develop synthetic organic chemistry. Through targeted total syntheses this project will investigate and learn about the highly sophisticated way nature utilises dimerizations to rapidly generate molecular complexity. This project will demonstrate the power of this biomimetic strategy by synthesising a wide variety of complex dimeric natural products ....Biomimetic Synthesis of Dimeric Natural Products. The aim of this research is to use nature as a source of inspiration and direction to improve and develop synthetic organic chemistry. Through targeted total syntheses this project will investigate and learn about the highly sophisticated way nature utilises dimerizations to rapidly generate molecular complexity. This project will demonstrate the power of this biomimetic strategy by synthesising a wide variety of complex dimeric natural products including phenylethanoids, alkaloids, lignans, terpenes and coumarins. The expected outcome will be uniquely efficient synthetic strategies that significantly surpass all previous approaches and new synthetic methodology that will be of broad use in organic synthesis.Read moreRead less
Using natural products to inspire discoveries in synthesis and biosynthesis. This project aims to understand the organic chemistry that occurs in the biosynthesis of unusual antibiotic natural products by marine microorganisms. In an interdisciplinary approach, proposed biosynthetic intermediates will be synthesised and screened against newly isolated enzymes from the microorganisms of interest. This will allow the elucidation of biosynthetic pathways, and aid the discovery of new chemoenzymatic ....Using natural products to inspire discoveries in synthesis and biosynthesis. This project aims to understand the organic chemistry that occurs in the biosynthesis of unusual antibiotic natural products by marine microorganisms. In an interdisciplinary approach, proposed biosynthetic intermediates will be synthesised and screened against newly isolated enzymes from the microorganisms of interest. This will allow the elucidation of biosynthetic pathways, and aid the discovery of new chemoenzymatic reactivity that may be broadly useful in organic synthesis. Non-enzymatic, predisposed organic reactions will also be uncovered during the project. The benefit of this project will be an improvement in our ability to synthesise potential antibiotics using a combined synthetic organic and chemoenzymatic approach. This could lead to useful new antibiotics in the future.Read moreRead less
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.

In this project, catalysis will be used to allow these ubiquitous building blocks to react in entirely new ways. In doing so new chemical reactions will be discovered that convert simple building blocks into sophisticated fine chemicals. The potential utility of the products is diverse and will enable future applications in fields focused on the preparation of functional materials. Read moreRead less
Extending the frontiers of organocatalysis: new reactions involving nucleophilic carbenes. High technology solutions to the problems of today and tomorrow require new materials designed for specific activities. This project will deliver new technologies for the rapid and efficient assembly of materials designed for function.
Challenges to organocatalysis. This project aims to use organocatalysis to generate organocatalytic C=C insertion, C-H functionalisation and carbonyl ylide/1,3-dipolar cycloaddition reactions. Organocatalysis has transformed the way chemical synthesis is performed. However, in the early years the focus of this discipline has primarily been enolate type chemistry, and more challenging reactions, such as those involving carbenoid intermediates, have not been contemplated. Previously such reactions ....Challenges to organocatalysis. This project aims to use organocatalysis to generate organocatalytic C=C insertion, C-H functionalisation and carbonyl ylide/1,3-dipolar cycloaddition reactions. Organocatalysis has transformed the way chemical synthesis is performed. However, in the early years the focus of this discipline has primarily been enolate type chemistry, and more challenging reactions, such as those involving carbenoid intermediates, have not been contemplated. Previously such reactions have only been achieved using transition metal catalysts. This project addresses this limitation, allowing the strengths of organocatalysis (abundance and diversity, access to enantiopurity, elemental sustainability) to affect the broader landscape of catalysis. This approach could present an opportunity to examine reactivity patterns, stereoselectivity and cascade design and may lead to new reaction technologies.Read moreRead less
