Syntheses of heteroaromatic carboxylic acids closely related to fusaric acid.

Abstract

In order to investigate the generality of a chain-elongation reaction observed in the metabolism of fusaric acid (5-butyl-2-pyridinecarboxylic acid) and its derivatives, various heteroaromatic (diazine, 1, 3-azole, and 1, 2-azole) carboxylic acids with a normal alkyl side-chain were synthesized.
