    • The invention describes novel nitrosated and/or nitrosylated H2 receptor antagonist compounds, and novel compositions comprising at least one H2 receptor antagonist compound that is optionally substituted with at least one NO and/or NO2 group, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase and/or at least one nonsteroidal antiinflammatory drug, antacid, bismuth-containing reagent or anti-viral agent. The invention also describes methods for treating and/or preventing gastrointestinal disorders; improving gastroprotective properties of H2 receptor antagonists; decreasing the recurrence of ulcers; facilitating ulcer healing; preventing and/or treating inflammations and microbial infections, ophthalmic diseases and disorders, multiple sclerosis, and viral infections; and decreasing or reducing the gastrointestinal toxicity associated with the use of nonsteroidal antiinflammatory compounds.

    • A process for the enantioselective synthesis of an (S)— or (R)-1-[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol and analogues or salt thereof are described. The method involves the steps of (a) reacting an (S) or (R) 4-benzyloxazolidinone with a mixed anhydride of a methyoxyphenylacetic acid under conditions which form a oxazolidinone, (4S)— or (4R)-4-benzyl-3-[methyoxyphenyl]acetyl]-oxazolidin-2-one, (b) treating the (4S)— or (4R)-4-benzyl-3-[(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one with an aprotic amine base and titanium chloride in a chlorinated solvent under conditions which permit formation of the corresponding anion, (c) mixing the corresponding anion with titanium chloride and cylcohexanone under conditions which permit an aldol reaction to form the corresponding (4S)— or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one, (d) hydrolyzing the (4S)— or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one to form a chiral acid (2S or 2R)-(1-hydroxycyclohexyl)-methoxyphenyl)acetic acid, (e) coupling the chiral phenylacid to a secondary amine to form an amide, and (f) reducing the amide to form an (S) or (R) 1[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol or a salt thereof.
