Chiral discrimination of ammonium neurotransmitters by C₃-symmetric enantiopure hemicryptophane hosts.


Enantiopure hemicryptophanes efficiently discriminate chiral ammonium neurotransmitters. The ephedrine and norephedrine molecules associate with hemicryptophane hosts to form 1:1 and 1:2 host-guest complexes. Binding constants are determined by fitting the ¹H nuclear magnetic resonance (NMR) titration curves to give β₁ and β₂ values, which are used to… (More)
