Abstract/OtherAbstract:
A pair of diastereomeric salen cavitands and their uranyl complexes combine a chiral (R,R) salen bridge, and an inherent chiral tris-bridged quinoxaline cup within the same molecule. Whereas the free ligands show a preference for the same enantiomer of an alpha-amino acid pair, the corresponding UO2 complexes display opposite enantiodiscrimination and exceptionally high enantioselectivities (KD/KL = 26.4).
