The Uses of 2,6-Pyridinedicarboxylic acid chloride

2,6-Pyridinedicarboxylic acid chloride was used as the reagent during the synthesis of pyridine-based polyamido-polyester optically active macrocycles. It was used as starting reagent during the synthesis of pyridine-bridged 2,6-bis-carboxamide Schiff′s bases. It was used in the synthesis of N,N′-bis(1-pyrenylmethyl)pyridine-2,6-dicarboxamide.

The Uses of 2,6-Pyridinedicarboxylic acid chloride

2,6-Pyridinedicarbonyl dichloride can be used as a starting material to synthesize:

• Pyridine-based polyamido-polyester optically active macrocycles by reacting with chiral diamine dihydrobromides.
• Pyridine-bridged 2,6-bis-carboxamide Schiff′s bases by treating with L-alanine or 2-methyl-alanine methyl esters.
• N,N′-bis(1-pyrenylmethyl)pyridine-2,6-dicarboxamide by reacting with 1-pyrenemethylamine hydrochloride in the presence of a base.

Synthesis

Pyridine-2,6-dicarboxylic acid (105 mg, 0.52 mmol) mixed with 7mL of thionyl chloride was heated to reflux for 3 hours. After the excess thionyl chloride was removed, a white solid was obtained and used for the following synthesis without further purifications.
