A regioselective synthesis of β- and γ-fluorinated ketones via silver-catalyzed ring opening is described. A variety of β- and γ-fluorinated ketones are efficiently prepared, respectively, from tertiary cyclopropanol and cyclobutanol precursors, providing a straightforward approach for the introduction of a fluorine atom into complex molecules. Preliminary mechanistic studies suggest that a radical-mediated

The invention relates to novel quinoline derivatives, processes for their preparation, pharmaceutical compositions containing them and their use as medicaments particularly in treating disorders of the central nervous system (CNS).
Cyclobutanols and cyclopropanols underwent ring-opening fluorination upon treatment with Selectfluor in the presence of a substoichiometric amount of a silver salt. The reaction provides an efficient method to synthesize γ- and β-fluoroalkyl ketones.

The invention provides bupropion analogue compounds capable of inhibiting the reuptake of one or more monoamines. The compounds may selectively bind to one or more monoamine transporters, including those for dopamine, norepinephrine, and serotonin. Such compounds may be used to treat conditions that are responsive to inhibition of the reuptake of monoamines, including addiction, depression, and obesity.
