Efficient synthesis of 5-bromo-2,3-dimethoxy-6-methyl-1,4-benzoquinone: key intermediate for preparing Coenzyme Q

The title compound, a key intermediate for preparing Coenzyme Qn family, was prepared in an excellent yield by a reaction sequence starting from the commercially available 3,4,5-trimethoxytoluene 1 via bromination, methoxylation and oxidation reactions. A

Coenzyme Q compound synthesis method

The invention relates to a coenzyme Q compound synthesis method, which comprises the steps of: dissolving substituted or unsubstituted 3, 4, 5-trimethoxytoluene in an organic solvent, carrying out a reaction on the obtained solution and an oxidant aqueous solution for 1-2h at a temperature of 20-80 DEG C under the catalysis of an acid, and carrying out extraction, water washing, reduced pressure distillation and recrystallization on the obtained crude product to obtain a coenzyme Q compound. Raw materials used in the method are cheap and easy to obtain, and no toxic or harmful waste gas or waste residue is generated in the reaction process; and reaction steps are few, the operation is easy and convenient, the product yield is high, and the method is suitable for industrial large-scale production.

Photochromic coenzyme Q derivatives: Switching redox potentials with light

Coenzyme Q is an important redox cofactor involved in a variety of cellular processes, and is thus found in several cell compartments. We report a photochromic derivative of coenzyme Q that combines the molecular structures of the redox active cofactor and a photochromic dye. Light irradiation triggers an electronic rearrangement reversibly changing the redox potential. We used this effect to control the intermolecular redox reaction of the photochromic coenzyme Q derivative with dihydropyridine in solution by light irradiation. On mitochondria, the altered redox properties showed an effect on the respiratory chain. The experiments demonstrate that the redox reactions can be initiated inside the system of interest through irradiation with light and the accompanied photoisomerization.
