Abstract (en)

[origin: WO2011003607A2] The invention relates to a method for separating a mixture having a first compound dissolved in a solvent, which first compound comprises at least one keto group, and having a second compound, which comprises a chiral carbon atom with a hydroxyl group, which was yielded from the stereoselective reduction of the keto group from the first compound. The mixture is brought into contact with an inorganic adsorber material and at least part of the second compound is adsorbed on the inorganic adsorber material, and a mixture depleted in the second compound is separated from the inorganic adsorber material.
