The use of an ortho-naphthoquinone catalyst enables a biomimetic alcohol dehydrogenase (ADH)-like oxidation protocol as green alternative to existing stoichiometric and metal-catalyzed alcohol oxidation reactions. The developed organocatalytic aerobic oxidation protocol proceeds through an intramolecular 1,5-hydrogen atom transfer of naphthalene alkoxide intermediates.
