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.

Two complementary Pauson-Khand annulation protocols for use with the gaseous alkene, ethylene, are described. These N-oxide promoted reactions (10 examples) are shown to proceed under both mild autoclave conditions or, more conveniently, at atmospheric pressure. The developed methodology has been utilised as the key transformation in the totalsynthesis of the sesquiterpene (+)-taylorione which has

The Suzuki-Miyaura-type cross-coupling reaction of potassium alkyltrifluoroborates with various alkenyl bromides in the presence of 10 mol % of PdCl(2)(dppf).CH(2)Cl(2) and 3.0 equiv of Cs(2)CO(3) in aqueous toluene at 80 degrees C provided the desired compounds in 49-95% yields. A variety of functional groups in the potassium alkyltrifluoroborates were tolerated under the basic conditions.
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.
