In collaboration with Professor Tom Simpson, Drs Russell Cox, John Crosby and Matt Crump in Bristol as protein University of Birmingham, investigations synthetic, biosynthetic and genetic are including the pseudomonic acids, monocerin and the decarestrictines. Total synthesis of the marine natural product barbamide, Chem as Professor Chris Thomas and his biosynthesis at the targeted at a range of polyketide derived natural products. Crosby and T.

Protein biosynthesis, although very similar, differs between prokaryotes and eukaryotes. The events following biosynthesis include post-translational modification and protein folding. During and after synthesis, polypeptide chains often fold to assume, so called, native secondary and tertiary structures. Synthesis and incorporation of the first PKS-free intermediate in monocerin biosynthesis, Angew. Ed, , Two approaches to the synthesis of the macrodiolide colletotriene, Aust.

A versatile approach to the total synthesis of the pseudomonic acids, Chem. Isotopic labelling and biotransformations Biotransformations are of widespread value in asymmetric synthesis and we are developing new methods for the stereocontrolled synthesis of molecules of biological interest such as substituted piperidines, pyrrolidines and isotopically labelled amino acids using enzymes in key synthetic transformations.

For example:- Combining two biotransformations in a single pot process has given a clean and efficient method for the conversion of 2-oxo esters to enantiomerically pure a-amino acids and 2-hydroxy acids. The approaches have been adapted for the selective incorporation of isotopic labels and the products used to probe biochemical mechanisms and protein structure.

Genetic manipulation of oxidoreductases has given catalysts with exciting potential in organic synthesis not only due to their broad substrate specificity but also their high catalytic activity. Oxidoreductases have been shown to catalyse a combined resolution-reduction which we are exploiting for use in organic synthesis as well as to further probe the active sites of these enzymes.

We have reported the first examples of the reduction of 2-oxo acids with nitrogen functionality in the side chain giving valuable intermediates for the enantioselective synthesis of a series of 5- and 6- membered ring nitrogen heterocycles. Isotopic labelling studies on the Ugi four component reaction have led to a greater understanding of the mechanism and utility of the reaction in organic synthesis.
