Optically active amino acid sulfoxide - and sulfone - derivatives, their preparation, their polymerization and use as adsorbents for the chromatographic racemate resolution

摘要

The invention relates to novel optically active amino acid derivatives of the general formula (I) IMAGE in which n, R, R1, R2, R3, X and A have the meaning indicated in the description, which contain sulphoxide or sulphone groups, two fundamental process routes for their preparation from sulphur-containing amino acids, the polymerisation of these monomers and the use of the polymers as optically active adsorbents for the chromatographic resolution of racemates into the enantiomers.
