Aminoalkohole, 4. Mitt.: Ein Trennverfahren zur Herstellung von enantiomerenreinem Midodrin
摘要:
Racemic midodrine chlorohydrate (rac-1) was N-protected to yield the racemic products rac-2a-c. These were converted into the diastereomeric O-acetals 3a-c/4a-c, which can easily be separated by chromatography. After removal of the N- and O-protective groups from 3a-b/4a-b, respectively, enantiomerically pure midodrine chlorohydrate R-1 and S-1 could be isolated.
