実験手順

To a dimethylformamide solution (20 ml) of 6-(10-acetoxydecyl)-2,3-dimethoxy-5-methyl-1-tetrahydropyranyloxybenzene (240 mg) is added bis(salicylidene)ethylenediiminocobalt(II) (14 mg), followed by stirring in oxygen streams at atmospheric temperature and pressure for 72 hours. The reaction product is isolated in the same manner as Example 7 and recrystallized from hexane. The above procedure yields 6-(10-acetoxydecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (110 mg) as orange-yellow needles melting at 37° C.-38° C.
