The palladium-catalyzed Suzuki−Miyaura coupling of pyridyl-2-boronic esters provided an efficient approach to useful biaryl building blocks containing a 2-pyridyl moiety. The convenient reaction protocol demonstrates its potentially wide applications in medicinal chemistry.

pocket of hSIRT1. A convenient access to these 3-(6-aryl pyridin-2-yl)indoles () was established the first ultrasound assisted heteroarylation approach involving a CC bond forming reaction between 6-aryl substituted 2-chloropyridine and indoles in the presence of AlCl. Indeed, the current approach revealed sonochemical replacement of the C-3 hydrogen of indole by the pyridine ring in a regioselective manner
