Abstract
A process for the preparation of an enantiomerically enriched amine, is performed by a) cleaving a racemic mixture of a reaction product of i) a chiral amine and ii) an acyl donor, in the presence of a hydrolase, to obtain a mixture of an enantiomerically enriched amide and an enantiomerically enriched amine; or b) reacting an amine with an acyl donor, in the presence of a hydrolase, to obtain a mixture of an enantiomerically enriched amide and an enantiomerically enriched amine; and c) separating the enantiomerically enriched amide from the enantiomerically enriched amine, wherein the acyl donor is a sulphonylacetic acid ester. The process (1) leads to high enantioselectivities, and (2) high reactivities, (3) is based on an acyl donor accessible in a simple manner, (4) is suitable for a large number of very different substrates and/or (5) is suitable for carrying out at high substrate concentrations.
