Palladium-Catalyzed Anilide ortho-Arylation and Subsequent One-Pot Cyclization to Phenanthridines
摘要:
[GRAPHICS]The palladium-catalyzed direct arylation of anilides possessing several N-acyl substituents has been demonstrated. Removal of the acyl group by base hydrolysis allows a short and efficient synthesis of 2-aryl or 2,6-diarylanilines. The method is functional group tolerant and allows the presence of chloride and bromide substituents on both the anilide and aryl iodide coupling components. The arylation products can be converted to phenanthridines by the reaction with trifluoroacetic anhydride.

Pharmaceutical compositions that bind to a predicted FK506 Binding Protein 52 (FKBP52) interaction surface on the androgen receptor hormone binding domain, otherwise known as FKBP52 Targeting Agents (FTAs) are provided. These compositions of the present invention are found to specifically recognize the FKBP52 regulatory surface on the androgen receptor and inhibit FKBP52 from functionally interacting with the androgen receptor. Compositions comprising the pharmaceutical composition, as well as methods of use, treatment and screening are also provided.
