OPTICALLY ACTIVE AMINO ACID SULFOXIDE AND AMINO ACID SULFONEDERIVATIVE,THEIR PRODUCTION,THEIR POLYMERIZATION,AND METHOD OF USING THEM AS ADSORBENTS IN CHROMATOGRAPHIC RESOLUTION OFRACEMIC MODIFICATION

摘要

The invention relates to novel optically active amino acid derivatives of the general formula (I) 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.
