Research Project: Artificial copper enzymes for photoredox catalysis

Co-Supervisor: Prof. Oliver Reiser (UR)
Industrial Mentor: Dr. Erika Tassano (Novartis)

Project abstract

Copper (I/II) catalysts are currently of great interest for applications in visible light photoredox chemistry, as they offer an alternative to precious metals such as ruthenium (II) or iridium (III) and allow to control the stereochemistry of the reactions. Therefore, we are working on introducing non canonical amino acids (such as BpyAla) in de novo protein scaffolds, in order to create a chiral environment to perform various stereoselective photoredox reactions (Atom transfer radical additions to olefins, oxo-azidation, oxo-amination…).

Project abstract

Deoxygenation reactions of aliphatic, non-benzylic alcohols and polyols represent an important subcategory of defunctionalization reactions, utilized for late-stage structural editing of complex molecules. Strategies for the activation of carbinolic C–O bonds have been amply developed, which proceed either through stoichiometric pre-activation of the O-atom to increase its nucleofugality, by catalytic C–O bond activation with – predominantly precious – transitions metals, or by C–O bond weaking via radical pathways.[1] While in all of these methods the H atom usually stems from a separate (stoichiometric) reagent, we are investigating a complementary, light-driven catalytic protocol based on a "hydrogen atom shuffling mechanism", in which the H atom of the newly formed C–H bond derives from the OH group of a substrate molecule.

Project abstract

In collaboration with the group of Prof. König a vanadium co-catalysed photochemical reaction is investigated via 51V-NMR spectroscopy. This novel approach should give insights in the reaction mechanism and active intermediates to help further develop and improve the reaction experimentally.

Studies towards strain-release activation of organic transformations harnessing quadircyclene intermediats as moelcular energy storage devices.

Do not „waste“ the strain release energy as heat, but use it for vibrational activation of a reagent to be turned over!
