The macromolecular nature of functional polymer catalysts deliver three distinct advantages over small molecule analogues: it may (1) bestow additional factors that can improve selectivity such as functional group co-operativity and steric strain; (2) provide differing polarity to the bulk solvent phase which may enhance reaction rate; and (3) facilitate catalyst recovery allowing for reuse.
Inspired by the intrinsic function of nature’s enzymes, we seek to develop recyclable, solution soluble, polymer-based organocatalysts that promote key organic transformations relevant for the synthesis of biologically active compounds, such as stereoselective desymmetrisation.
The project will focus on the use of RAFT polymerization as it is compatible with a broad range of functional groups typically used in asymmetric organocatalysis (i.e. ureas, thioureas, alcohols, phosphines, N-heterocyclic carbene precursors). Substrate specificity will be probed through competitive reaction processes. Fine tuning the periodicity of catalytic functionality along the polymer backbone and tailoring of the hydrophobic-hydrophilic balance of the system are expected to enhance catalyst activity and selectivity.
The successful candidate will be trained in a range of advanced synthetic techniques used in the preparation of functional small molecules and precision polymers. Laboratory work and characterization will be undertaken within the University of Wolverhampton’s new Science Centre, the Rosalind Franklin building, which houses a broad range of state-of-the-art research facilities suitable for undertaking this synthetic project.
