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.
一种制备光学活性trans-2,6-二甲基吗啉的方法:(i)将混合的trans-2,6-二甲基吗啉与D-苯甘酸反应,(ii)去除形成的D-苯甘酸盐和一个对映体的trans-2,6-二甲基吗啉,使其与另一个对映体的trans-2,6-二甲基吗啉分离,(iii)分离所需的光学活性trans-2,6-二甲基吗啉。
