چکیده انگلیسی
High-performance liquid chromatographic methods were developed for the separation of the enantiomers of thirteen unusual β-3-homo-amino acids and three of its ethyl esters on a chiral stationary phase containing (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid as chiral selector. The effects of the mobile phase composition and the acidic modifiers on the separation were investigated. The structures of the substituents in β-position substantially influenced the retention and enantioseparation. The influence of ionic strength on the enantioseparation was established experimentally. The elution sequence was determined in all cases.
