    摘要: A process for the enantioselective enzymatic reduction of compounds which comprise a steroid structure (ABCD) including one or several heteroatoms, one or several double bonds and/or one aromatic component in the ring structure and have at least one oxo group at position 3, 7, 11, 12 or 17 in the steroid ring system or in the α-position at any carbon moiety on the steroid skeleton (=oxosteroid compound), wherein the oxosteroid compound is reduced with a hydroxysteroid dehydrogenase in the presence of a cofactor NADH or NADPH, is characterized in that a) the oxosteroid compound is provided in the reaction at a concentration of ≧50 g/l, b) the oxidized cofactor NAD or NADP formed by the hydroxysteroid dehydrogenase is regenerated continuously by oxidation of a secondary alcohol of general formula RXRYCHOH, wherein RX, RY independently represent hydrogen, a branched or unbranched C1-C8-alkyl and Ctotal≧3, or by oxidation of a C4-C6-cycloalkanol, and c) an additional oxidoreductase/alcohol dehydrogenase is used for the oxidation of the secondary alcohol of general formula RXRYCHOH or of the cycloalkanol, respectively.
