This invention concerns compositions for the treatment of urinary frequency, urinary urgency and urinary incontinence comprising (R)-N-[4-[2-[[2-hydroxy-2-(pyridin-3-yl)ethyl]amino]ethyl]phenyl]-4-[4-(4-tri-fluoromethylphenyl)thiazol-2-yl]benzenesulfonamide and pharmaceutically acceptable salts thereof. In another aspect, this invention concerns combination therapy for urinary frequency, urinary urgency and urinary incontinence wherein one of the active agents is (R)-N-[4-[2-[[2-hydroxy-2-(pyridin-3-yl)ethyl]amino]ethyl]phenyl]-4-[4-(4-tri-fluoromethylphenyl)thiazol-2-yl]benzenesulfonamide and pharmaceutically acceptable salts thereof.
5-disubstituted dihydrofurans. Hydrolysis of electrooxidation products with ion enchange-resin, followed by the treatment with base gave rethrolones. Furthermore, this method was applicable for the synthesis of 2-alkyl-4-hydroxycyclopentenone.

Dynamic kineticresolutionthrough metal complex induced racemization and Candida antarctica lipase mediated enantioselective acetylation of a model hydroxy-ketone: 4-hydroxy-2-methylcyclopent-2-en-1-one and its selected derivatives, has been studied. Racemization of the hydroxy-ketone was efficiently affected by [RuCl2(cymene)]2 complex–triethylamine while Shvo's catalyst triggered an intramolecular

4-hydroxy-4-methylcyclopent-2-enone and related 4-substituted cyclopent-2-enones towards 1,3-dipolar cycloaddition with nitrile oxides is studied. The reactions are always completely regioselective while the diastereofacialselectivity depends on the nature of the substituents. Remarkably, the reaction of 4-acetoxycyclopent-2-enone shows complete regio- and diastereo-facial selectivity.
The present invention is directed to certain phenyl pyrrolidine ether compounds which are useful as neurokinin-1 (NK-1) receptor antagonists, and inhibitors of tachykinin and in particular substance P. The invention is also concerned with pharmaceutical formulations comprising these compounds as active ingredients and the use of the compounds and their formulations in the treatment of certain disorders, including emesis, depression, and anxiety.
