Novel 1,2-diarylcyclobutenes: Selective and orally active cox-2 inhibitors
摘要:
A series of novel 2,3-diaryl-2-cyclobuten-1-ones have been synthesized and have been evaluated with respect to their ability to inhibit the isozymes of cyclooxygenase, COX-I and COX-2. 4,4-Dimethyl-2-phenyl-3- [4-(methylsulfonyl)phenyl]cyclobutenone 22 was found to be highly selective for inhibition of COX-2 and was orally active (ED(50) = 2.4 mg/kg) in the rat paw edema model.

We report on a three-componentpalladium-catalyzed coupling strategy for accessing a wide range of 1,4-diketones, which represent important precursors to heterocycles. Our method relies on a carbonylative Heck reaction employing substituted allylic alcohols, aryl iodides, and carbon monoxide. The reaction conditions are mild and do not require high CO pressure, and a wide functional group tolerance
