Abstract/OtherAbstract:
A novel single isomer of positively charged β-cyclodextrin, mono-6-deoxy-6-((2S,3S)-(+)-2,3-O-isopropylidene-1,4-tetramethylenediamine)-β-CD (MIPTACD) was designed and synthesized in seven steps starting from commercially available (2R,3R)-tartaric acid. The chiral resolution abilities of the new cationic chiral selector were studied by capillary electrophoresis using 10 different dansyl (Dns)-amino acids and N-acetylphenylalanine (N-Ac-Phe) as model analytes. The effects of running buffer pH and chiral selector concentration on the separation selectivity, resolutions, and migration times of analytes were studied in detail. MIPTACD shows a very good chiral recognition ability even at very low concentrations at the investigated pH values, as shown by the very large values of selectivity and resolution towards amino acids enantiomers to be assessed.
