A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.
The present invention relates to substituted pyrrolidinyl-3-yl-alkyl-piperidines, their stereoisomers, and pharmaceutically acceptable salts thereof and processes for preparation of the same. The compounds of the present invention are useful in their pharmacological activities such as tachykinin antagonism, especially substance P and neurokinin A antagonism, and the like. Compounds having the property of tachykinin antagonism are indicated for conditions associated with neurogenic inflammation and other diseases described herein.
