We have identified a new series of N-aryl azacycles as sodium channel blockers, which showed good potency on Na(v)1.7 in FLIPR-based and electrophysiological functional assays. Analogs from this series possessed selectivity over hERG, reasonable oral exposure in rat PK studies and are predicted to have limited CNS penetration. (C) 2014 Elsevier Ltd. All rights reserved.
An efficient method for the copper-catalyzedtrifluoromethylation of terminal alkenes with an electrophilic trifluoromethylating reagent has been developed. The reactions proceeded smoothly to give trifluoromethylated alkenes in good to excellent yields. The results provided a versatile approach for the construction of Cvinyl-CF3 bonds without using prefunctionalized substrates.

aldehyde/ketones via N2H4 mediated deoxygenative couplings. Compared with one-electron umpolung of carbonyls to alcohols, this two-electron umpolung strategy realized reductive deoxygenation targets, which were not only applicable to the regioselective alkylation of a broad range of 2/4-alkene substituted pyridines, but also amenable to challenging 3-vinyl and steric-embedded internal pyridines as well as their
