A Separation Procedure for the Preparation of Enantiomerically Pure Midodrine
Noe,Knollmüller,G?rtner
, p. 159 - 165 (2007/10/03)
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 gro
