Our host institutes – the Department of Chemistry at the University of Oxford, and the Green Chemistry Centre of Excellence at the University of York – offer a truly diverse range of research interests that spans many fields of chemical synthesis and technological innovation. The CSHP CDT programme will take advantage of many complementary themes to develop cutting edge chemistry, while focusing on training that embeds sustainable, circular chemistry in the mindset of our cohorts.
Students in the CSHP CDT undertake a 44-month substantive research project focussing on any of the three global challenges of Human Health, Food Security, and Energy and Materials.
Before applying to the CDT, applicants are encouraged to read through the available projects and list their three preferred projects in order of preference in their application form. Applicants will need to apply directly to the host institution of their preferred projects.
Further details on the research projects are available through direct contact with the supervisors or on application.
* Below is an updated project list, following the first round of admissions.
Bicyclo[n.1.1]alkanes (BCAs) have emerged as important building blocks in contemporary drug design. These bridged ring structures are usually prepared from ring-opening reactions of [n.1.1]propellanes, and additions to bicyclo[1.1.0]butanes (BCBs). However, current routes to [n.1.1]propellanes rely on the use of alkyl/aryllithium reagents to effect closure of their three-membered rings, while BCB synthesis is also frequently reliant on strongly basic reaction conditions. This project seeks to address these shortcomings by developing contemporary strategies to improve the sustainability and scalability of propellane and BCB synthesis, and to apply these methods to the functionalisation of BCAs.

Modern life is impossible to imagine without polymers. However, the environmental persistence and reliance on fossil resources of most used polymers make them unsustainable. In collaboration with SCG Chemicals, this project will investigate the utilisation of abundant natural carbohydrate feedstocks to produce recyclable and degradable bio-based plastics, whose properties can compete with or complement those of polyolefins such as polyethylene, towards a circular economy of plastics with a low carbon footprint.

Molecules containing stereogenic phosphorous (V) atoms are commonplace in bioactive medicines and agrochemicals ranging from: antivirals, to cardiovascular treatments, to herbicides, yet their syntheses are often challenging, specific to the target molecule, and use stoichiometric amounts of non-recyclable chiral auxiliaries.

Surfactants are used in virtually every industry, and there is a high demand for biodegradable surfactants to prevent pollution and increase process efficiency. Some control over transient surfactant concentration has recently been achieved in an oscillating chemical system. This project involves learning how to control surfactant concentration using electrochemistry – and to give us the ability to turn-on or turn-off the presence of surfactants on demand.

There is increasing interest in the use of surfactants to tackle key elements of antimicrobial resistance (AMR). It is our hypothesis that the effectiveness of, and opportunities provided by, such agents could be dramatically improved through the incorporation of a “photoswitch” motif into the structure of the surfactant. This work will develop and study such photodynamic surfactants to pioneer a new modality to tackle AMR.

There is significant interest in sp3-rich heterocyclic scaffolds for medicinal chemistry due to their success in proceeding through the drug development process. In this project, a set of novel 3D bifunctional building blocks will be designed and synthesised; systematic coverage of 3D chemical space and 3D vectors will be achieved by computational analysis.

While naphthalene and equivalent heterobiaryl rings are often encountered in drugs, candidates and lead molecules, they can be susceptible to cytochrome P450-mediated metabolism and exhibit flat, sp2-rich structures and are almost invariably derived from fossil fuel sources, limiting their current and future utility. Yet, few viable alternatives have been described. In this project we propose to build on our preliminary findings that aryl-fused bicyclo[3.1.1]heptanes (aryl BCHeps) can serve as effective bioisosteric replacements for naphthalene or (iso) quinolines, and can be accessed via an unusual photosensitiser-induced mechanism and extend into other unexplored problematic heterobiaryl bioisosteres.

Adhesives play a critical role in many technologies from construction, transportation, electronics to consumer goods. There are growing environmental concerns, legislation and customer pressure to deliver more sustainable adhesives and to ensure they maximise recycling of other components. Adhesives which can bond/de-bond on demand and which are degradable after use are particularly important. Here, we will develop new lower carbon footprint sustainable polymers, sourced from biomass and waste carbon dioxide, as debondable, recyclable and degradable adhesives.
