The selenious acid oxidation of 2‐aryl‐7,7‐dimethyl‐5,6,7,8‐tetrahydro‐5‐quinazolones 2a – c leads to the corresponding 2‐aryl‐7,7‐dimethyl‐6,8‐epidiseleno‐5,6,7,8‐tetrahydro‐5‐quinazolones 3a – c . This is the first observation of the formation of an intramolecular unsymmetrical diselenide by selenious acid oxidation and reports the first derivatives of the new ring system 2,3‐diselenabicyclo[3.2.1]octane.
