D-amino acids are an important class of chiral reagents and chiral intermediates.
At present, most of the production of D-amino acids is to prepare racemates by synthetic methods, and then resolve them to obtain optical isomers. Using asymmetric conversion method, using (2R,3R)-tartaric acid as the resolving agent, in the presence of butyraldehyde, the racemization of L-proline and the combination of D-proline and (2R,3R)-tartaric acid The two-step reaction of salt formation and crystallization proceeded simultaneously. The total yield reached 82%.
