Date Sep. 12, 1996The present invention relates to photochemically cross-linked derivatives of general formulae (IA) and (IB), wherein R is a polysaccharide radical in which the OH groups have been esterified as OR' groups or converted into a carbamate (urethane), R1, and R2 are each independently lower alkyl or unsubstituted or substituted aryl, X is a direct bond or phenylene, m is 0 or 1, and n is 0 or an integer from 1 to 20, to processes from the preparation thereof and to the use thereof. The compounds of general formula (IA) and (IB) can be used as supports in the chromatographic separation of enantiomers. |
