Abstract

Reversed-phase high-performance liquid chromatographic methods were developed for the enantioseparation of ten unusual β-3-homo-amino acids. The underivatized analytes were separated on a chiral stationary phase containing (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid as chiral selector. The effects of organic and acidic modifiers and the mobile phase composition on the separation were investigated. The structures of the substituents in the β position substantially influenced the retention and resolution. The elution sequence was determined in some cases: the S enantiomers eluted before the R enantiomers.
