Asymmetrische Synthese von allylischen Alkoholen mittels Palladium-katalysierter asymmetrischer Transformation von allylischen Carbonaten und Synthese neuer Sulfoximin-Phosphane
… areas of study. The first part focuses on the asymmetric synthesis of synthetically interesting allylic alcohols by Palladium-catalyzed allylic substitution. For this substitution reaction the hydrogen carbonate ions are used as nucleophil and racemic allylic carbonates or acetates as racemic …

Organoselenium redox-catalyzed, enantioselective syn-difunctionalization of alkenes
… high enough to serve as proof of concept for an asymmetric transformation. Further evaluation of a variety of catalyst scaffolds led to the development of rigid tetralin-derived diselenides. The best performing diselenide in this class afforded the syn-dichloride product in an enantiomeric ratio …
