Bioinspired Total Synthesis of Complex Natural Products

Supervisory Team: Dr Jonathan George

This project will involve the total synthesis of stereochemically complex natural products using new methods inspired by biosynthesis. The synthetic work will have potential applications in medicinal chemistry, the elucidation of biosynthetic pathways, and the structural assignment of natural products. 

Background:

The use of natural products as antibiotics and anticancer agents has revolutionised human healthcare. However, many natural products are highly complex molecules isolated in minute amounts from their natural source. The total synthesis of these molecules is therefore crucial to allow their future application in medicine. This research project aims to develop new ways of constructing 3-dimensionally complex natural products using strategies inspired by their biosynthesis. In particular, we will target the synthesis of natural products of mixed biosynthetic pathways in which the dearomatization of aromatic rings converts simple, flat structures into stereochemically complex molecules. This work will expand the toolkit of complexity-generating organic reactions that can be applied in medicinal chemistry.

Research in the George Group: 

We have developed many concise, biomimetic total syntheses of complex molecules – summarised in the following review (Acc. Chem. Res. 2021 https://pubs.acs.org/doi/10.1021/acs.accounts.1c00019). 

Sometimes our syntheses help to decipher biosynthetic pathways in collaboration with biochemists (Nat. Chem. 2017 https://www.nature.com/articles/nchem.2829; Angew. Chem. Int. Ed. 2018 https://onlinelibrary.wiley.com/doi/abs/10.1002/anie.201804351). We have also integrated modern methods of photoredox catalysis (Angew. Chem. Int. Ed. 2019 https://onlinelibrary.wiley.com/doi/10.1002/anie.201814089), photochemistry (J. Am. Chem. Soc. 2022 https://pubs.acs.org/doi/10.1021/jacs.2c09978) and biocatalysis (Angew. Chem. Int. Ed. 2019 https://onlinelibrary.wiley.com/doi/10.1002/anie.201812432) into our total synthesis projects. 

Many of our projects involve the biosynthetically-inspired structure revision of natural products (Angew. Chem. Int. Ed. 2022 https://onlinelibrary.wiley.com/doi/full/10.1002/anie.202200420), and even the prediction and isolation of new natural products. Our ultimate goal is to discover new ways to make complex natural products as quickly and easily as possible – sometimes achieving this in just one step! (Chem. Sci. 2023 https://pubs.rsc.org/en/Content/ArticleLanding/2023/SC/D2SC05377B). 

You will receive expert training in synthetic organic chemistry and other specialist areas as required by the project, either from the George Group or appropriate collaborators. You will also gain extensive experience of a range of analytical techniques including advanced NMR analysis and single crystal x-ray diffraction. Mentorship in writing high-impact publications and delivering engaging scientific presentations will also be provided.
