Popis: Four regioselectively modified amylose derivatives with three different substituents at the 2-, 3-, and 6-positions were prepared and their enantioseparations in HPLC were examined. Investigations indicated that the nature as well as the arrangement of the substituents significantly influenced their enantioseparations and each derivative exhibited characteristic chiral recognition. Amylose 2-benzoyl-3-(3,5-dimethylphenylcarbamate or 3,5-dichlorophenylcarbamate)-6-((S)-1-phenylethylcarbamate) exhibited chiral resolving abilities comparable to the commercial available amylose tris(3,5-dimethylphenylcarbamate)-based column, Chiralpak AD and the racemic compounds shown in this study were most effectively resolved on these two derivatives. The influence of mobile phase on chiral resolution was also examined.
