A process for obtaining optically pure 2 - aminonitriles or 2 - aminoamides of optically impure mixtures, racemic mixtures or the optically pure enantiomers of the opposite configuration

摘要

The present invention is a chemical method for obtaining an optically pure 2-aminonitrile or a 2-aminoamide from (1) an optically impure mixture, (2) a racemic mixture, or (3) the optically pure enantiomer of the opposite configuration, in an amount greater than actually present, by use of optically active acids with a ketone or an aldehyde catalyst. Yields of greater than 70 percent of one enantiomer are obtained from racemic mixtures in very short time periods.
