## Abstract The reaction of the 4,4‐dialkylated 2‐cyclohexenones **1** or **2** with a twofold excess of a secondary amine **3** affords the 2‐amino‐1,3‐cyclohexadienes **4** and **5**, respectively. Irradiation (Ξ» ≧ 300 nm) of the morpholino derivative **4a** yields a mixture of the isomeric 3‐mor
