Abstract

|
|
The resolution of N-trifluoroacetyl (N-TFA) ter-isopropylesters of Ala, Ile, Lau, Val and Phe by gas chromatography on the (S)-5-isobutyl-N3-phenyl-2-thiohydantoin as stationary phase was investigated. The phase was employed at several column temperatures (140°CN200°C) and the separation factors were 1.18^1.45 range for five amino acid enantiomers. The possible mechanism of chiral recognition was investigated by NMR technique and the association constant(L) was calculated as 201.3(r=0.98) for alanyl derivative.
