    摘要: The present invention describes an enzymatic process for preparing enantiomer-enriched α-hydroxycarboxylic acids and amides which comprises, in one step, the conversion of a carbonyl compound to the corresponding acid/amides via the intermediate stage of a cyanohydrin. The invention also provides a reaction system operating in such a way and a whole-cell catalyst that is advantageous for use for this reaction.

    摘要: The present application relates to a reaction system in which chemically valuable compounds can be obtained in high enantiomer purities with the aid of a coupled enzymatically operating transformation process. The coupled enzymatically operating reaction system in this context comprises an enzymatic transformation reaction which proceeds with the consumption of a cofactor, and recycling of the cofactor consumed, which proceeds enzymatically, wherein the procedure is carried out in a homogeneous aqueous solvent system comprising an organic hydrocarbon having at least two hydroxyl or ether groups.
