DESCRIPTION:Prof. Dr. Golo Storch\, Mainz: Flavin Catalysis: From Biomimet
 ic \nTransformations to New Reactivity\n\nFlavoenzymes are responsible for
  a multitude of different transformations in nature\, many of which are we
 ll-understood mechanistically. Learning from these activities and adapting
  them for syntheti-cally valuable reactions in the organic laboratory is o
 ne of our main aims. While some reactions work with the isolated (–)-rib
 oflavin cofactor\, others require carefully designed synthetic variants\, 
 which we explore and apply. Following our strategy\, we have developed cat
 alytic methods inter alia for reduction\, oxidation\, hydrogen atom transf
 er (HAT)\, and oxygenation.\nIn their excited state\, flavins are strong s
 ingle-electron oxidants\, and they also serve as sensitizers after intersy
 stem crossing (ISC). We recently discovered that the sensitization activit
 y is significantly enhanced though an unusual ring-contraction\, which pro
 ceeds with flavin 1 under basic conditions.
