A novel and efficient racemization catalyst, Pd/layered double-hydroxide-dodecyl sulfate anion, was prepared and used in the dynamic kinetic resolution (DKR) of arylamines. The undesired enantiomer was completely racemized at 55 C, allowing the catalyst to be compatible with biocatalysts. DKR proceeded smoothly and showed a broad substrate scope, with good conversion and high product enantiomeric excesses (eep). The system could be reused more than 30 times without loss of conversion and eep value.

Efficient self-disproportionation of enantiomers of several non-racemic chiral amines was achieved through conversion to N-acetamides and subsequent MPLC using an achiral column. The MPLC of these non-racemic N-acetamide derivatives gave the chart having a clear boundary between two fractions. Thus, in the less polar fraction, remarkable enantiomer enrichment was observed (>99%ee), while the ee of more polar fraction was considerably reduced. The magnitude of the enantiomer enrichments and depletions strongly depended on substituent on the amino group.
