Abstract

The macrocyclic glycopeptide chiral selectors are natural molecules produced by bacterial fermentation. Purified and bonded to silica particles, they make very useful chiral stationary phases (CSP) with a broad spectrum of applicability in enantiomeric separation. The macrocyclic glycopeptide CSPs are multimodal, the same column being able to work in normal phase mode with apolar mobile phase, in reversed-phase mode, or in polar ionic mode with 100% alcoholic mobile phase of adjusted pH. The role of the carbohydrate units is described as well as the critical charge–charge docking interaction responsible for the amino acid enantiomer recognition. The complimentary phenomenon is also exposed.
