organic compound with the formula HO2C(CH2)5CO2H. Derivatives of pimelic acid are involved in the biosynthesis of theamino acid calledlysine . Pimelic acid is one methylene longer than a relateddicarboxylic acid , adipic acid, a precursor to many polyesters and polyamides. It is the final member of the mnemonic used to aid recollection of the order of the first six dicarboxylic acids using their common (not IUPAC) nomenclature: [http://en.wikipedia.org/wiki/Dicarboxylic_acid]Pimelic acid has been synthesized from
cyclohexanone and fromsalicylic acid . [Snyder, H. R.; Brooks, A. L.; Shapiro, S. H. "Pimelic Acid from Cyclohexanone" and Müller, A. "Pimelic Acid from Salicylic Acid"Organic Syntheses, Collected Volume 2, p.531 (1943).http://www.orgsyn.org/orgsyn/pdfs/CV2P0531.pdf] In the former route, the additional carbon is suppled by dimethyloxalate , which reacts with the enolate.References
