      Abstract: Convenient syntheses of dipicolinic or   chelidamic acid derivatives including   4-X-6-diethylcarbamoyl-pyridine-2-carboxylic acid (X = H, Cl, Br)   and 4-chloro-6-(3-oxo-3-phenylpropionyl)pyridine-2-carboxylic   acid methyl ester are described. These compounds are important   synthons for the synthesis of non-symmetric tridentate aromatic   chelating agents as well as for the design of ditopic ligands   targeted for the elaboration of functional dimetallic helicates.   (C) 2001 Elsevier Science Ltd.
