  Absolute Configurational Assignment of Acyclic Hydroxy Carboxylic Acids:  A New Strategy in Exciton-Coupled Circular Dichroism

  摘要：

  A new strategy in exciton-coupled circular dichroism (ECCD) is described for the configurational assignment of alpha-hydroxy carboxylic acids. Using 9-anthryldiazomethane (4), carboxyl groups can be selectively derivatized with a chromophore suitable for exciton coupling. In combination with the 2-naphthoate chromophore linked to the alpha-hydroxy group, the absolute stereochemistry of alpha-hydroxy carboxylic acids can be easily deduced from a single CD measurement. The usefulness of the new method is demonstrated with a series of alpha-hydroxy acids with different side chains. The developed microscale method is also useful for chiral amino acids and natural products containing carboxyl groups or similar structural units.

  Several azine derivatives have been prepared and structurally characterized by spectroscopic and single-crystal X-ray diffraction analysis. Two of them, viz. naphthalene based (A10) and anthracene based (A11) show fluorescence enhancement in the presence of Ag+ in aqueous-methanol. Moreover, A11 efficiently tracks Ag+in vitro endophytic bacteria infected rice root tissue. Experimental results have
