Descripción

Application

3-Pyridinylboronic acid can be used as a reagent for:

• Phosphine-free Suzuki-Miyaura cross-coupling reactions.
• Regioselective Suzuki-Miyaura coupling and tandem palladium-catalyzed intramolecular aminocarbonylation and annulation.
• N-arylation using copper acetylacetonate catalyst.
• Copper-mediated cyanation and regioselective cyanation of electron-rich benzenes.

It can also be used to prepare:

• New linear poly(phenylpyridyl) chains by Suzuki coupling.
• Oligopyridyl foldamers as mimics of a-helix twist.
• Many highly significant therapeutic enzymatic and kinase inhibitors and receptor antagonists.
• Pyridine substituted pyridinium N-(2′-azinyl)aminides by reacting with dibromo pyridinium aminides via Suzuki coupling reaction.
