Enantioseparation of analogs of the dipeptide alanyl-phenylalanine by capillary electrophoresis using neutral cyclodextrins as chiral selectors.

•Separation of novel dipeptides using cyclodextrins as chiral selectors•Migration order dependence on the cavity size and substitution pattern of the cyclodextrins•pH-dependent reversal of the enantiomer migration order•Rationalization of the enantiomer migration order based on complexation constants and complex mobilities
