, p. 541 - 543 (2010)
Chiral discrimination of α-amino acids has been realized by a C 2-symmetric homoditopic receptor, which is based on a binaphthyl chiral skeleton with 2,2′diisopropoxy substituents and a common binding side arm, (o-carboxamido)-trifluoroacetophe

Two new receptors, a cavitand-salen (2) and a uranyl-cavitand-salen (3), for the selective molecular recognition of chiral ammonium ion pairs, where the amino acid is the countercation or counteranion of the ion pair, were designed and synthesized. UV/Vis

A new heteroditopic chiral uranyl-salen complex incorporating two pyrenyl groups was designed and synthesized for the recognition of ammonium salts, tetrabutylammonium (TBA) and tetramethylammonium (TMA) amino acids. UV/Vis measurements indicate the formation of 1:1 host-guest complexes with high association constants and an excellent en-antiomeric discrimination between the two enantiomers of phenylalanine-TMA. T-ROESY NMR experiments confirm cation-π and CH-π interactions between the TBA and TMA cations and the two pyrenyl arms, leading to the strong stability of the complexes. This is the first report of a uranyl receptor able to recognize chiral carboxylate guests.
CHIRAL AMINOACID CONTAINING ACYCLIC LIGANDS-I. SYNTHESES AND CONFORMATIONS

, p. 2055 - 2060 (2007/10/02)
Synthesis and spectral properties of optically active acyclic ligands, containing two (S)-phenylalanine residues (3a-f) are described.The synthesis is achieved by two different routes.Conformational studies in different solvents are performed by dilution and temperature-dependent experiments of 1H and 13C NMR spectroscopy.
