Synthesis of 7,9-didecarboxymethoxatin (4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2-carboxylic acid) and comparison of its chemical properties with those of methoxatin and analogous o-quinones. Model studies directed toward the action of PQQ requiring bacterial oxidoreductases and mammalian plasma amine oxidase
Pyrroloquinoline quinone derivatives were synthesized as model compounds of a novel coenzyme PQQ. The 2-mono- and 2,9-dicarboxylic acid derivatives 1b and 1d and the 1-methylated derivative If were synthesized relatively easily from the intermediates 5 and 4 of the PQQ-synthesis. The 2, 7-dicarboxylic acid derivative 1e was also synthesized via a combination of the Japp-Klingemann reaction and Fischer indolization.
