Metal catalysed reactions in organic synthesis. The major aim of this project is to develop highly efficient metal-catalysed routes to pharmaceuticals, e.g. new antibiotics and other commercially important organic molecules.
Particular attention will be paid to developing systems which facilitate the addition of readily available, cheap small molecules, e.g. hydrogen and carbon monoxide, to unsaturated organic molecules with high regio- and stereoselectivity.

Particular attention will be paid to developing systems which facilitate the addition of readily available, cheap small molecules, e.g. hydrogen and carbon monoxide, to unsaturated organic molecules with high regio- and stereoselectivity.
Worldwide demand for enantiomerically pure chiral molecules (i.e. one mirror-image form) continues to rise. New metal-catalysed asymmetric syntheses will help meet this challenge. Tandem metal-catalysed reactions will be used to prepare new heterocyclic compounds with potential as specific metal binding agents and biosensors.Read moreRead less

Synthesis of Bioactive Metabolites from Myxobacteria. The crocacins and apicularens are two diverse groups of biologically active molecules isolated from myxobacteria. Crocacins A-D are dipeptides which show antifungal activity and are highly cytostatic in mammalian cell cultures.

Gas phase studies of the interactions of electrons with peptide ions: structure assignment and fundamentals. Electron-induced reactions are fundamental to a wide range of processes that underlie many areas of science and technology, ranging from planetary atmospheres, industrial plasmas to living tissues.

Electron-induced reactions are fundamental to a wide range of processes that underlie many areas of science and technology, ranging from planetary atmospheres, industrial plasmas to living tissues. Since ionizing radiation is believed to be a major cause of damage to living cells, understanding electron interactions with biological molecules is essential to predict the consequences of exposure. Structure determination of biomolecules is at the heart of identifying, diagnosing and potentially developing treatments for diseases, and thus another important reason for studying these interactions is the potential to develop new mass spectrometry based analytical methods.Read moreRead less

Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unchartered area! We will examine the fundamental chemistry (unimolecular and bimolecular reactions) of these systems and build upon some exciting preliminary results which suggest potential applications (e.g. as a proteomics tool to sequence and distinguish between leucine and isoleucine residues in peptides).Read moreRead less
