prepared. Structure-activity relationship (SAR) studies indicated that the in vitro antibacterial potency was the following order: 1-(1,1-dimethyl-2-fluoroethyl) greater than 1-[1-methyl-1-(fluoromethyl)-2-fluoroethyl] greater than 1-[1,1-(difluoromethyl)-2-fluoroethyl] substituents. In the quinolone series the monofluoro-tert-butyl derivatives were found to possess better in vitro antibacterial activity
