Nortemann B, A Glasser, R Machinek, G Remberg, H-J Knackmuss (1993) 5-hydroxyquinoline-2-carboxylic acid, a dead-end metabolite from the bacterial oxidation of 5-aminonaphthalene-2-sulfonic acid. Appl Environ Microbiol 59 1898-1903. 

Anthanthrone is synthesized from naphthostyril (105), which is saponified to form l-aminonaphthalene-8-carboxylic acid (106). Naphthostyril itself is prepared from 1-naphthylamine with phosgene in the presence of dry aluminum chloride. 

Thus, on heating perchlorates of 5-alkoxy-l-aminonaphthalene 125 (R = Me, Et) with alkyl carboxylic anhydrides in the presence of catalytic ammounts of perchloric acid, N-protonated 2-alkyl-benzo[cd]indolium...
