Research

Our research interests are in catalysis and synthetic organic chemistry, and the contribution that they can make to the fields of medicine and natural products. We concentrate on developing new catalytic methodologies for synthetic organic chemistry and asymmetric synthesis and then employing our chemistry to make biologically important natural products.

Our work is directly relevant to the pharmaceutical industry and the research group is (or has been) supported by multi-national companies including Merck, AstraZeneca, GlaxoSmithKline, Lilly, Novartis, Roche, Aventis and Pfizer. The facilities available for research in our labs in the CRL are second to none.

The research group consists of four part II’s, twelve DPhil students and four postdoctoral assistants. We meet two/three times per week to discuss advances in the laboratory and hold problem sessions to highlight recent developments in the literature.

We are an active and vibrant research group with a positive dynamic and friendly atmosphere. Excellent support is given to new part II’s and DPhil students in the form of mentorship by a senior group members. Our research interests are wide ranging, encompassing osmium-catalysed processes, Birch reduction of pyrroles and pyridinium salts, carbohydrate chemistry and catalytic ring closing metathesis as a strategy for the formation of aromatic heterocycles. With each new catalytic method that we develop, we are also keen to show that it is useful in total synthesis. In this regard, the group has built up significant expertise in the synthesis of natural products; some of our current targets are shown below.

Oxidation: One research theme is the controlled oxidation of alkenes with catalytic osmium reagents. Our work on the tethered aminohydroxylation of allylic carbamates has encompassed an understanding of the mechanism and introduced a new set of N-O based re-oxidants into the catalytic aminohydroxylation regimen (the result is a much more powerful and high yielding aminohydroxylation procedure). This methodology allowed us to prepare the aminocyclitol (-)-hygromycin in a particularly efficient manner. Our work culminated in a completion of the synthesis of the natural product in only 17 linear steps (and 10% overall yield) by using a Mitsunobu glycosylation that allowed the formation of the difficult glycoside linkage with good stereoselectivity.

Our investigations into the osmium catalysed formation of THFs and pyrrolidines from diols and aminoalcohols, revealed the advantages of utilising the Os(IV)-(VI) couple, avoiding the presence of Os(VIII). We also uncovered an OMs displacement/ hydride shift sequence, followed by intramolecular trapping of the oxonium ion to form a trans-THF (supported by deuterium labelling). The combination of double oxidative cyclisation and a hydride shift was used in the synthesis of the natural products (+)-cis-sylvaticin and (+)-sylvaticin.

Partial Reduction We have a longstanding interest in developing the partial reduction of aromatic heterocycles using single electron reducing agents such as (catalytic) LiDBB. Our work has been able to reduce pyrroles, pyridines and furans in a selective and high yielding manner, and the heterocycles that are prepared via this chemistry have lots of potential for natural (and medicinal) product synthesis. In fact, each of these aromatic ring systems has been used as the starting point in the synthesis of complex and biologically active natural products.

By studying the mechanism using cyclic voltammetry (with R. G. Compton) we have  been able to understand the processes that take place and design new arenes for partial reduction, thus allowing greater scope for synthetic work.
