Abstract
| - The tetrahydroxyl derivative of BINOL, (S)- or (R)-1, and its analogues are synthesized. (S)- or (R)-1can be used to conduct the enantioselective recognition of chiral amino alcohols. In comparison withBINOL, the two additional hydroxyl groups of (S)- or (R)-1 have increased the binding of this compoundwith the amino alcohols and significantly improved the fluorescence quenching efficiency. The fluorescenceresponses of (S)- or (R)-1 toward amino alcohols are compared with those of its analogues (R)-4 and(R)-6. It shows that the interaction of the central naphthyl hydroxyl groups of (S)- or (R)-1 with thesubstrates is responsible for the observed fluorescence quenching, and the two additional alkyl hydroxylgroups increase the quenching efficiency.
