The present application provides novel pyridine compounds and pharmaceutically acceptable salts or prodrugs thereof. Also provided are methods for preparing these compounds. These compounds are useful in inhibiting CYP 17 activity by administering a therapeutically effective amount of one or more of the compounds to a patient. By doing so, these compounds are effective in treating conditions associated with CPY17 activity. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment, the disease is cancer, such as prostate cancer.

A palladium-catalyzed aerobic and ligand-free Suzuki reaction in aqueous ethanol has been developed for the synthesis of N-heteroaryl substituted 9-arylcarbazolyl derivatives. A number of N-heteroaryl halides, namely 2-halogenated pyridines, 2-bromoquinoline, 5-bromopyrimidine and 2-chloropyrazine, were coupled with 4-(9H-carbazol-9-yl)phenylboronic acid (CPBA) or 9-phenyl-9H-carbazol-3-ylboronic acid
A Zwitterionic Palladium(II) Complex as a Precatalyst for Neat-Water-Mediated Cross-Coupling Reactions of Heteroaryl, Benzyl, and Aryl Acid Chlorides with Organoboron Reagents
A zwitterionic palladium(II) complex has been found to be an efficient catalyst for Suzuki–Miyaura cross‐coupling reactions of aryl and heteroaryl organoboron reagents with various heteroaryl chlorides, aryl‐ and heteroarylmethyl chlorides, and aryl acid chlorides in neat water.
