Molecular migrations and efficient synthesis
At the heart of his dissertation – with results published in Nature in 2024 – is the development of new methods for the targeted transformation of alkenes into more complex products. These compounds are key building blocks across the chemical industry, from pharmaceuticals to petrochemicals. The new approach opens up faster and more resource-efficient synthetic routes.
“Our breakthrough came from addressing the limitations of classical methods. While most reactions occur at the two carbon atoms forming the double bond, we aimed to break this paradigm,” explains Dr Bruțiu. “Our approach enables, for the first time, the targeted functionalization of more remote positions within a molecule.”
The key concept is “charge relocation”: by introducing a reactive acyl fragment, a positive charge is generated in the alkene and can be deliberately shifted to a new position within the molecule. There, it can be harnessed for further transformations, enabling efficient access to previously difficult-to-reach structures.
Importantly, the method does not require additional molecular fragments, so-called directing groups, which often need to be removed after the reaction. Instead, the reagent simultaneously acts as both reactant and directing element. This elegant strategy significantly simplifies synthetic routes and broadens their scope: for example, the bioactive natural product 4-ipomeanol, which is used in medical research, can be synthesised in a single step rather than five.
About Dr Bogdan Bruțiu
Bogdan Bruțiu completed his Bachelor’s degree at the University of Vienna. He obtained his Master’s degree in 2019 in the group of Nuno Maulide, where he completed his PhD in 2024. His work had already been recognised in 2021 with a DOC fellowship from the Austrian Academy of Sciences. Since 2025, he has been a postdoctoral researcher in the group of Prof. Jeffrey Bode at ETH Zurich. In collaboration with Synple Chem AG, he is currently working on the development of automated reaction protocols, supported by a grant from the Swiss Innovation Agency Innosuisse.
About the Karl Schlögl Award
The Karl Schlögl Prize is awarded annually by the Austrian Academy of Sciences (OeAW). It recognises outstanding doctoral theses in synthetic, physical, analytical, and theoretical chemistry, primarily carried out at Austrian universities. The award ceremony took place on 24 March at the Austrian Academy of Sciences.
