The synthesis of 1,4-benzothiazine-2-carboxylicacid1-oxides as agents which mimic quinoloneantibacterial, are described. The key step includes intramolecular cyclization of phenylsulfinyl acrylates 17 and 18 which are prepared in six steps from 11. None of new target compounds showed interesting antibacterial activity in vitro against the tested strains.
