An efficient method for the synthesis of fluoropyridines via the fluorodenitration reaction is reported. The reaction is mediated by tetrabutylammonium fluoride (TBAF) under mild conditions without undue regard to the presence of water. The fluorodenitration is general for 2- or

Eight nitropyridinesulfonamides and pyridinesulfonamide N-oxides as their bioisosteres were prepared and evaluated for anticoccidial activity. Of these compounds, 2-, 4- and 5-nitropyridine-3-sulfonamides and pyridine-2- and -3-sulfonamide N-oxides were found to be active against Eimeria tenella. Thus, the relative positions, ortho
