Hydrogen Bonds and Ion Pairs in Enantioselective Photochemistry (B02)

• Subject Area: Organic Molecular Chemistry - Synthesis and Characterisation
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 444632635

Hydrogen bonds serve as non-covalent interactions to temporarily recruit substrates in an assembly with a photocatalyst. The project revolves around two catalyst classes displaying directed bonding motifs and providing a chiral cavity in which enantioselective photochemical reactions can occur. In work package 1, a lactam/amide binding motif will be employed for substrate coordination, and the catalysts display an azabicyclo [3.3.1] nonan-2-one backbone connected to a single chromophore. In work package 2, chiral phosphoric acids will be used, with the option to install one or two photocatalytic entities at the backbone rendering the catalysts either C1 or C2 symmetric.
