The present application relates to compounds and methods for reducing the severity of convulsant activity or epileptic seizures, or for the treatment of chronic or acute pain.

Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.

The present invention provides a novel process for producing 2,6,6-trimethyl-2-cyclohexene-1,4-dione (keto-isophorone) by catalytic oxidation of 3,5,5-trimethylcyclohexa-3-ene-1-one (-isophorone) with hydrogen peroxide as the oxidant. In particular, the novel process includes phase transfer reagent in a biphasic system including an organic phase and an aqueous phase wherein the biphasic system includes 1) a tungsten polyoxyometallate as catalyst and hydrogen peroxide, and/or 2) a mixture of a) a mineral acid, b) hydrogen peroxide, and c) a metal tungstate.
