The invention relates to fused piperidine amides useful as inhibitors of ion channels for the treatment of pain. The invention also provides pharmaceutically acceptable compositions comprising the compounds of the invention and methods of using the compositions in the treatment of various disorders.
Directly utilizing abundant and inexpensive sources of aliphatic carboxylic acids is highly attractive for the synthesis of CF2H- and CH3-containing compounds. Herein, we report a versatile photoinduced iron-catalyzed platform for hydrodifluoromethylation and hydromethylation of alkenes without the need of additional stoichiometric oxidants. These two transformations are accomplished by a visible-light-induced

A silver‐mediated oxidative difluoromethylation of styrenes and vinyl trifluoroborates with TMSCF2H is reported for the first time. This method enables direct and facile access to CF2H‐alkenes from abundant alkenes with excellent functional‐group compatibility. Moreover, this Ag/TMSCF2H protocol could further enable a series of radical difluoromethylation reactions of a wide array of substrates, offering
