Pseudosymmetry and chiral discrimination in optical resolution via diastereoisomeric salt formation. The crystal structures of (R)- and (S)-N-methylamphetamine bitartrates (RMERTA and SMERTA)
The structures of the diastereoisomericsalts of (R)- and (S)-N-methylamphetamine bitartrates (RMERTA and SMERTA) have been determined by X-ray crystallography. Comparison of these crystal structures provides an insight into the mechanism of opticalresolution via diastereoisomeric salt formation. The very small difference between the two crystal structures indicates that specific interactions such
