Abstract
Process for enhancement of enantioselectivity in the enzymatic separation of (R)- and (S)-enantiomers of an asymmetric alkynol, a lipase and in the presence of at least one vinyl ester, in which the acid component has at least 4 C atoms, an organic solvent and with the addition of water. Also disclosed is a process for enhancement of enantioselectivity in the enzymatic separation of (R)- and (S)-enantiomers of an alcohol with the aid of the abovementioned vinyl ester under addition of a second vinyl ester having at least 2 C atoms less in the alkyl chain than the vinyl ester used as esterifying agent.
