Cyclomaltooligosaccharide (cyclodextrin)-assisted enantiomeric recognition of benzo[lmn][3,8]phenanthroline-derived amino acids

Formation of self-assembly molecular aggregates and cyclomaltooligosaccharide (cyclodextrin) molecular aggregates with benzo[lmn][3,8]phenanthroline-derived amino acids is presented. The nature of the molecular aggregates was studied by negative-ion electrospray-ionization mass spectrometry (ESIMS). The enantiomeric recognition was demonstrated by NMR enantiomeric discrimination of the amino acid derivatives in aqueous solutions of cyclodextrins.
