, p. 3830 - 3860 (2007/10/02)
The synthesis of the following chromone dicarboxylic acids is described: 4-oxochromene-2,7-dicarboxylic acid, 6-methyl-4-oxochromene-2,8-dicarboxylic acid, 7-hydroxy-4-oxochromene-2,8-dicarboxylic acid, and 4-oxochromene-3,6-dicarboxylic acid. 4-Oxochromene-2,3-dicarboxylic acid 2-ethyl ester has been synthesized as well as 4-oxochromene-2,6,8-tricarboxylic acid.Some derivatives of these acids are described and the relative stability of carboxy groups attached to the chromen-4-one ring system is discussed.
