Recent trends in the chemistry of pyridine N-oxides

This review describes the synthesis and reactions of pyridine N-oxides within the last ten years. The first part survyes the different synthetic methods which include ring transformation, classical oxidations using peracids, the use of metalloorganic oxidizing agents and cycloaddition reactions. The second part survys the reactions of pyridine N-oxides including the deoxygenation, nucleophillic reaction and cycloaddition to N-O bond.
