eng Abstract:
In this work, new enantioselective material based on α-methylbenzylamine as the chiral selector (recently utilized by our group in the preparation of chiral\nmembranes) covalently attached to Merrifield resin beads is proposed and discussed as a potentially cost-effective alternative to typically expensive stationary phase materials. It is shown that charged chiral methylbenzylamine works as an enantioselective anion exchanger potentially suitable for the separation of chiral acids, such as N–protected amino acid, or non-steroidal anti-inflammatory drugs (NSAID), such as ibuprofen. In a glass column chromatography experiment, racemic N–(tert–butoxycarbonyl) tryptophan was partially separated, reaching enantiomeric excess in eluates of around 10%.\n
