Improved syntheses of fluorinated tertiary butylamines
摘要:
Two new and efficient methods using cyclic sulfamidate and nitrone chemistry were developed for the synthesis of the sterically congested 1,1-dimethyt-2-fluoroethylamine (1), 2-fluoro-1-(fluoromethyl)-1-methyl ethylamine (2) and 2-fluoro-1,1-bis-(fluoromethyl)-ethylamine (3).

prepared. Structure-activityrelationship (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

Compounds of formula I, including their salts, as well as compositions and methods of using the compounds are set forth. The compounds have activity against hepatitis C virus (HCV) and may be useful in treating those infected with HCV.
