Ullmann Coupling

New 4-substituted 9,10-anthraquinones (6 compouds) with amino derivations fragments were synthesized through the substitution of the bromaminic acid by amines using the Ullmann coupling reaction. The structures of the synthesized compounds were determined using LC-MS, 1H NMR, 13C NMR spectroscopy, and elemental analysis data.

Inflammatory Processes

The sulfonamidic moiety is much encountered in structures of bioactive compounds. In the present paper the studies on the sulfonamidated aryloxyalkylcarboxylic acids are extended by their attaching on certain substrata able to confer some special biological properties to the final products, such as anti-tumor and antioxidant actions useful in treating inflammatory processes, ulcer, convulsions and diabetes, as well as a herbicidal action. The stepwise syntheses of the sulfonamidated aryloxyalkylcarboxylic acid derivatives and their characterization by elemental analysis data and IR, 1H-NMR and UV-Vis spectral measurements are described. The newly obtained compounds could show potential pharmaceutical and herbicide properties.

7-benzylideneamino-5H-thiochromeno[2,3-b]pyridin-5-ones and 9-benzylideneamino-5H-thio- chromeno[2,3-b]pyridin-5-ones, on reaction with ethyl pyruvate to afford 1-ethoxycarbonyl-3-phenyl-12H- pyrido[3',2':5,6]thiopyrano[3,2-f]quinoline-12-ones and 4-ethoxycarbonyl-2-phenyl-7H- pyrido[3',2':5,6]thiopyrano[3,2-h]quinoline-7-ones respectively by the two different methods. These products were precipitated by addition of ethanol, water (1:1), were purified by recrystalizing from appropriate solvents and were characterized from their IR, 1H-NMR, mass spectra and elemental analysis data.
