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

The project aims to employ hydrogen bonding and ion pairing interactions in enantioselective photochemical reactions. Enantioselectivity is achieved (a) by the use of chiral lactams or Brønsted acids which display an internal, light-collecting sensitizing unit to transfer energy exclusively to a bound substrate or (b) by devising substrates which are activated towards photochemical excitation by a chiral Brønsted acid. In the former scenario, emphasis is placed on catalytic deracemization reactions. The work with chiral acids will rely largely on the binding motif of carboxylic acids and imines to these acids.
