Development of an Azanoradamantane‐Type Nitroxyl Radical Catalyst for Class‐Selective Oxidation of Alcohols.

The title catalyst is prepared on gram scale in an eight-step sequence and affords superior results to TEMPO and its 1-methylazaadamantane analogue, not only for the class-selective oxidation of primary alcohols to aldehydes in the presence of a secondary alcohol, but also for the selective one-pot oxidation to carboxylic acids as well as for oxidative lactonization.
