Dimethylformamide → Idebenone

Participants

Reaction Steps

To a dimethylformamide solution (50 ml) of 6-(10-hydroxydecyl)-2,3-dimethoxy-5-methylphenol (2.53 g) is added bis(salicylidene)ethylenediiminocobalt(II) (salcomine) (0.1 g) and the mixture is stirred in oxygen streams at atmospheric temperature and pressure for 72 hours. The solvent is then distilled off and the product is extracted with ether. The ethereal layer is washed with water and dried over anhydrous sodium sulfate, and the solvent is distilled off. The above procedure yields 6-(10-hydroxydecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (2.32 g) as orange-yellow needles melting at 52° C.
