, p. 1291 - 1293 (1999)
Three nitro musks, musk xylol 1, musk ketone 2 and musk ambrette 3, were prepared in good to moderate yield by direct polynitration of the respective aromatic materials with nitrogen dioxide in the presence of ozone.

The present disclosure relates to compounds of Formula (I) and process of obtaining the same. Said compounds of Formula (I) is employed in the syntheses of pyrroloquinoline quinone (PQQ), 4,5-dioxo-4,5-dihydro-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid 2-allyl ester, 5-ethoxy-5-hydroxy-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid, 5- hydroxy-6-(1,1,4-trioxo-1 lambda* 6*-1,2, 5 -thiadiazolidin-2-yl)-1H-indole-2-carboxylic acid and its pharmaceutically acceptable salts. Said syntheses of compounds via. compounds of Formula (I) as intermediates employ minimum number of steps resulting in a shorter process and has improved efficiency along with many other advantages.
