This invention relates to deuterated analogs of etifoxine of Formula 1, solvates, prodrugs, and pharmaceutically acceptable salts thereof, as well as to methods for their preparation and use, and to pharmaceutical compositions. Briefly, this invention is generally directed to deuterated analogs of etifoxine as well as to methods for their preparation and use, and to pharmaceutical compositions containing the same.
Mg-promoted reduction of a mixture of aromaticketones (or imines) and aliphatic carbonyl compounds in N,N-dimethylformamide (DMF) brought about unique mixed pinacol type of cross coupling to give unsymmetrical vicinal diols (or amino alcohols) or α-hydroxyketones in good to moderate yields. The reaction may be initiated by electron transfer from magnesium metal to an aromatic carbonyl compound possessing a
Microspheres are produced by contacting a solution of a macromolecule or small molecule in a solvent with an antisolvent and a counterion, and chilling the solution. The microspheres are useful for preparing pharmaceuticals, nutraceuticals, cosmetic products and the like of defined dimensions.
