12 Abstract Process for enhancement of enantioselectivity in the enzymatic separation of (R)- and (S)-enantiomers of an asymmetric alkynol in the presence of a lipase and in the presence of at least one vinyl ester, in which the acid component has at least 4 C atoms, and if appropriate in the presence of an organic solvent and/or in the presence of water and 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.
