Oxidations of alkanes, alkenes, and aromatic rings with pyridine N-oxides are efficiently catalyzed by rutheniumporphyrins under mild conditions. We show here that the oxidation of N-acyl cyclic amines with RuIVtetraarylporphyrin dichloride-2,6-substituted pyridine N-oxides directly gives N-acyl amino acids in modest to good yield via oxidative C-N bond cleavage.
