A palladium-catalyzed regioselective C-2 arylation of 7-azaindoles, indoles, and pyrroles with arenes has been developed. The study unveils that a critical substrate dependent acid concentration is essential for achieving exclusive...
The present invention provides compounds of the formula:
that are 5HT3 receptor antagonists and are therefore useful for the treatment of diseases treatable by inhibition of 5HT3 receptor such as emesis, pain, drug addiction, neurodegenerative and psychiatric disorders, and GI disorders. Also provided are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
