The title compound, 2-methoxy-4,4-dimethyl-2,5-cyclohexadienone (V), was prepared from 2-methoxy-4,4-dimethyl-2-cyclohexenone (VIa). A methanolic solution of V was irradiated with a 200 W mercury lamp at -3℃ to give 2,2-dimethoxy-6,6-dimethylbicyclo [3. 1. 0] hexan-3-one (X) and 6,6-dimethoxy-5,5-dimethyl-2-cyclohexenone (XI) in yields of 36.5 and 7.8%, respectively. On the other hand, a methanolic solution of V was irradiated in the presence of a catalytic amount of sulfuric acid to give only 2-methoxy-4-(1-methoxy-1-methylethyl)-2-cyclopentenone (XIII) in 35.4% yield. The behavior of V and VIa in the presence of a catalytic amount of acid is also described.
