Notes:
The (aR, aR, aR) and (aS, aS, aS) enantiomers of a chiral macrobicyclic ligand with a bicapped tris(binaphthol) structure were synthesized. Complexation of gallium(III), chromium(III) and iron(III) centres in the chiral cavities of these two ligands yielded exclusively one octahedral configuration in each case: the (aR, aR, aR) enantiomer gave a A complex and the (aS, aS, aS) enantiomer a complex. These assignments were established by CD spectroscopy for chromium and iron centres and by molecular modelling.
