Enantioselective complexation of excitatory amino acid derivatives by chiral, ... Roland J. Pieters and Frangois Diederich* Laboratorium fur Organische Chemie, ETH-Zentrum, Universitatstrasse 16, CH-8092 Zurich, Switzerland ... Chiral, cage-like C3-symmetrical receptors are prepared in a short, modular synthesis and found to be able to enantiose- lectivly recognise NZ-Glu in both titration and solubilisa- tion studies. ... Nature has evolved selective binding sites ...
