Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information ....Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information on the nature of the reactive intermediates themselves, the nature of the products formed, and the reaction dynamics, and they are of fundamental importance for an understanding of chemical reactivity generally. The methodology developed will be applicable to the investigation of a wide range of processes.Read moreRead less

Synthesis of new heterocyclic analogues of isoflavones. Intake of high dietary isoflavonoid phytoestrogens has been linked to low prevalence of hormone-dependent cancers such as breast and prostate cancer, and heart disease. The isoflavones resemble endogenous estradiol in structure, and have been shown to display weak estrogenic activity. Novogen Limited is pioneering the development of novel drug candidates based on isoflavones.

New mechanisms and methods in carbene and nitrene chemistry. Carbenes and nitrenes are highly reactive intermediates of theoretical and mechanistic significance and synthetic versatility in organic chemistry. In spite of high reactivity, selective and high-yielding reactions can be performed, leading to products that may be difficult or impossible to synthesise by other methods. They have practical applications in photo-affinity labelling of biomolecules, and photolithography. This project will ....New mechanisms and methods in carbene and nitrene chemistry. Carbenes and nitrenes are highly reactive intermediates of theoretical and mechanistic significance and synthetic versatility in organic chemistry. In spite of high reactivity, selective and high-yielding reactions can be performed, leading to products that may be difficult or impossible to synthesise by other methods. They have practical applications in photo-affinity labelling of biomolecules, and photolithography. This project will contribute fundamental knowledge of the nature and reactions of these species by using direct spectroscopic observation. We are proposing the occurrence of novel types of reactions and the formation of several new reactive intermediates as well as a technique for the stabilization of reactive intermediates by incorporation into macrocyclic frameworks.Read moreRead less
Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety ....Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety of electron transfer mediators can be examined in a readily controlled and systematic way simply through the choice of cation. In this way, the role played by molecular recognition in the modulation of long-range electron transfer can be evaluated. This work will lead to designing better artificial solar energy converters and molecular electronic devices.Read moreRead less

The Baylis-Hillman Reaction: Asymmetric Organocatalysis and Applications. Many drugs come in two chiral mirror images (enantiomers) where the therapeutic effect is usually associated with only one while the other has no effect or can be harmful as was the case with thalidomide. Chemical reactions that yield just the desired mirror image, or enantiomer, and not the other are therefore in great demand and heavily pursued by the pharmaceutical, fine chemical and materials industries as a frontier ....The Baylis-Hillman Reaction: Asymmetric Organocatalysis and Applications. Many drugs come in two chiral mirror images (enantiomers) where the therapeutic effect is usually associated with only one while the other has no effect or can be harmful as was the case with thalidomide. Chemical reactions that yield just the desired mirror image, or enantiomer, and not the other are therefore in great demand and heavily pursued by the pharmaceutical, fine chemical and materials industries as a frontier technology. This project will result in the development of novel catalytic reactions that allow the synthesis of chiral chemicals in a cost-efficient and green manner needed by many industries, and also training of students with highly desirable synthetic skills to lead the next wave in pharmaceuticals and biotechnology.Read moreRead less
