Abstract (German)

Die Methode der enantioselektiven Decarboxylierung wurde angewendet, um Enantiomeren-angereicherte alpha-Aminosäurederivate und alpha-Fluorketone zu erhalten. Als Substrate wurden 2-N-Acetylamino-2-alkylmalonsäuremonoethylester beziehungsweise beta-Keto-benzylester verwendet. China-Alkaloide und Derivate davon wurden als Katalysatoren eingesetzt. Die besten erhaltenen Ergebnisse waren ...

Translation of the abstract (English)

The method of enantioselective decarboxylation was applied to obtain enantioenriched alpha-amino acid derivatives and alpha-fluoro ketones. 2-N-acetylamino-2-alkylmalonic monoethylesters respectively benzyl beta-ketoesters were applied as substrates. Cinchona alkaloids and derivatives of them were used as catalysts. The best results obtained were ethyl N-acetyl-L-phenylalaninate with 70% ...
