| titleOfInvention | Catalytically reductive ring closure for 1-acylamino-3,4-phthaloylacridones |
| abstract | The present invention relates to an advantageous novel process for producing 1-acylamino-3,4-phthaloylacridones by a hydrogenating ring-closure reaction of 1-acylamino-4-anilidoanthraquinone-2'-carboxylic acid esters. n The ring-closure reaction according to the invention to the acridone ring is performed under mild conditions, with regard to temperature and alkalinity of the reaction medium, with the use of a hydrogenating catalyst. The first step to effect the ester formation can be carried out, as a single-vessel reaction, with the use of a polar solvent as the reaction medium, and of an alkylphosphoric acid dialkyl ester as the esterifying agent. |
