Novel and Efficient Procedure for the Preparation of Two Pyridine Dicarboxylic Acid Derivatives

New strategies for the synthesis of two pyridine dicarboxylic acid derivatives namely; 4‐(2‐(2,6‐dicarboxypyridin‐4‐yl)vinyl)pyridine‐2,6‐dicarboxylic acid and 2,6‐bis(2‐(2,6–dicarboxy‐pyridin‐4‐yl)vinyl)pyridine have been described. New oxidant used is a good example of green chemistry technology and the synthesis procedure harvest a high‐purity product at a high yield.
