| Abstract: | Four novel derivatives of BINOL bearing S-tryptophan unit have been prepared and the structures of these compounds characterized
by IR, MS, 1H and 13C NMR spectroscopy and elemental analysis. The enantioselective recognition of these receptors has been studied by fluorescence
titration and 1H NMR spectroscopy. The receptors exhibited different chiral recognition abilities towards N-Boc-protected amino acid anions
and formed 1:1 complexes between host and guest. Receptors exhibit excellent enantioselective fluorescent recognition ability
towards the amino acid derivatives. |
