Abstract
The invention relates to a process for the enantioselective enzymatic reduction of secodione derivatives. The secodione derivative is reduced with an oxidoreductase/dehydrogenase in the presence of NADH or NADPH as a cofactor. The secodione derivative is used in the reaction batch at a concentration of ≧10 g/l and the oxidized cofactor NAD or NADP formed by the oxidoreductase/dehydrogenase is regenerated continuously.
