title: Triazole-linked host compounds for chiral-discrimination toward amino acid ester guests.
abstract: The chiral-discriminating abilities of new triazole-linked host compounds (6, 7) toward amino acid esters were evaluated by the FABMS/EL-guest method. Two types of host appending saccharide derivatives were synthesized by the copper-catalyzed Huisgen-1,3-dipolar cycloaddition (CuAAC). Host compounds binding constants and chiral-discriminating abilities toward the enantiomeric alanine esters were evaluated by UV method in chloroform. The structural requirements of triazole-linked hosts were determined by their chiral-discriminating behaviors.
