The palladium-catalyzeddirect acetoxylation and arylation of 2-aryloxypyrimidine has been described. The aromatic C−H bonds may be functionalized in moderate to excellent yields providing a facile method for the synthesis of phenol derivatives, which show antimycobacterial and herbicidal activities.

The invention provides a series of substituted aryl pyrimidine compounds and the use of these compounds as therapeutics to treat or prevent neurodegenerative disorders, including Parkinson's disease. Compounds of the invention are also able to treat the symptoms of such diseases and therefore represent a new treatment modality for ameliorating chronic and acute conditions. The compounds of the invention are capable of selectively potentiating the activity of the Nurr1:RXRα heterodimer, and are able to treat diseases or conditions associated with aberrant Nurr1:RXRα function. The invention further provides methods for treating neurodegenerative disorders by administration of Nurr1:RXRα activating agents.
Etherification of Functionalized Phenols with Chloroheteroarenes at Low Palladium Loading: Theoretical Assessment of the Role of Triphosphane Ligands in CO Reductive Elimination
tolerates very important functions in various positions, such as cyano, methoxy, amino, and fluoro groups, which is useful to synthesize bioactive molecules. DFT studies furthermore demonstrate that triphosphane ligands open up various new pathways for the CO reductive elimination involving the third phosphanegroup. In particular, the rate for one of these new pathways is calculated to be about 1000 times
