  Synthesis and Antibacterial Activity of Novel 7-Substituted 6-Fluoro-1-methylene-4-oxo-4H-[1,3]thiazeto[3,2-a]quinoline-3-carboxylic Acid Derivatives

  摘要：

  A series of 7-substituted 6-fluoro-1-methylene-4-oxo-4H-[1,3]thiazeto[3,2-a]quinoline-3-carboxylic acid derivatives (2) and (3) was prepared and evaluated for antibacterial activity. These compounds were obtained by the treatment of the 1-methanesulfonyloxymethyl or 1-fluoromethyl thiazetoquinolone-3-carboxylates (12, 14 and 20) with potassium hydroxide. Compounds (2) and (3) showed excellent in vitro antibacterial activity against both gram-negative and gram-positive bacteria including quinolone and Methicillin-resistant Staphylococcus aureus.
