We report a practical and highly efficient protocol for the arylation of pyridine N-oxides with arylboronic acid through palladium-catalyzed Suzuki reaction in water. This ligand-free Suzuki reaction is performed in the presence of diisopropylamine and gives 2- or 3-arylated pyridyl N-oxide derivatives in good to excellent yields within 1 h. (C) 2014 Chun Liu.

Synthesis of Pyridine-<i>N</i>-oxide–Borane Intramolecular Complexes by Palladium-Catalyzed Reaction of 2-Bromopyridine-<i>N</i>-oxides with Alkynyltriarylborates
Pyridine-N-oxide-borane Intramolecular complexes having an aza-stilbene pi-framework were synthesized by the palladium-catalyzed reaction of 2-bromopyridine-N-oxides with alkynyltriarylborates.

stabilized by the formation of a hydrogen bond and favorable hydrophobic contacts. The affinity of MBPs is dependent on a large number of factors including donor atom identity, orientation, electrostatics, and van der Waals interactions. These results suggest that metal coordination by metalloenzyme inhibitors is a malleable interaction and that it is thus more appropriate to consider the metal-binding
