Abstract
A method of enantiomerically enriching chiral cyanohydrins is disclosed that involves selective cleavage of the unwanted enantiomer into its cleavage products HCN and the corresponding aldehyde or ketone by use of an enantioselective dehydrocyanation catalyst, coupled with simultaneous removal of at least one of the dehydrocyanation products.
