Abstract:
A process for preparing optically active trans-2,6-dimethylmorpholine by (i) reacting racemic trans-2,6-dimethylmorpholine with D-mandelic acid, (ii) removing the salt formed from D-mandelic acid and one enantiomer of trans-2,6-dimethylmorpholine from the other enantiomer of trans-2,6-dimethylmorpholine and (iii) isolating the desired optically active trans-2,6-dimethylmorpholine.
