An economic four-step synthesis of 2,6-dimethoxy-1,4-benzoquinone was achieved in 68% overall yield starting from aniline. The reaction sequence involved conversion to 1,3,5-tribromoaniline, deamination, methoxylation, and oxidation. The procedure is operationally simple and amenable to scale-up production.

The title compound was prepared by a reaction sequence starting from 2, 3, 4, 5-tetramethoxytoluene via Blanc chloromethylation reaction, oxidation and alkylation. The described method provides a good yield of the heterocyclic-Coenzyme Q analogue and is suitable for the synthesis of other analogues.

The title compound, a key intermediate for preparing Coenzyme Qn family, was prepared in high yield by a reaction sequence starting from the commercially available 3, 4, 5-trimethoxy-benzadehyde via Wolff–Kishner reduction, Vilsmeier–Haack reaction, Blanc chloromethylation reaction, Dakin reaction and oxidation.

Isocyanides undergo formal [1 + 4]cycloaddition with 2-acetyl-1,4-benzoquinone to afford isobenzofuran-4,7-quinone derivatives.
