The invention relates to aryl substituted compounds of Formula (I) : and pharmaceutically acceptable salts, prodrugs, or solvates thereof, wherein Het, G, A, R, and n are defined as set forth in the specification. The invention is also directed to the use of compounds of Formula I to treat a disorder responsive to the blockade of sodium channels. Compounds of the present invention are especially useful for treating pain.
osmium-catalyzed dihydroxylation has uncovered that electron-deficient olefins are converted into the corresponding diols much more efficiently when the pH of the reaction medium is maintained on the acidic side. Further studies have identified citric acid as the additive of choice, for it allows preparation of very pure diols in yields generally exceeding 90%. As described here, a much wider range of olefin classes
cost-effective cis-dihydroxylation reaction of acrylate derivatives was achieved. The reaction proceeded in acetone with an imidazolium salt as catalyst to furnish the dihydroxylation of olefins at 0–5 °C using KMnO4 as the oxidant. This efficient and non-aqueous protocol was highly suitable for the large-scale preparation of cis-dihydroxylated compounds from the corresponding acrylate derivatives
