| Abstract;The chiral recognition of .ALPHA.-amino acids in aqueous media has been achieved by using multiply charged cyclodextrins(CDx) and .BETA.-CDx as host molecules. The chiral recognition of N-acetylamino acids by per-NH3+-.BETA.-CDx and amino acid methyl esters by per-CO2-.BETA.-CDx have been studied by means of 1H NMR spectroscopy. The chiral recognition of a dipeptide (AlaTrpOMe) by per-CO2-.BETA.-CDx and .BETA.-CDx has been examined by means of 1H NMR spectroscopy and capillary zone electrophoresis(CZE). The NMR data show that both CDxs prefer (R,R)-isomer of AlaTrpOMe. The binding constants for complexation with per-CO2-.BETA.-CDx are higher than that for .BETA.-CDx. (author abst.) |
