Efficient lewis acid ionic liquid-catalyzed synthesis of the key intermediate of coenzyme Q10 under microwave irradiation

An efficient synthesis of a valuable intermediate of coenzyme Q10 by microwave-assisted Lewis acidic ionic liquid (IL)-catalyzed Friedel-Crafts alkylation is reported. The acidity of six [Etpy]BF4-based ionic liquids was characterized by means

Synthesis of the key intermediate of coenzyme Q10

(2′E)-1-(3-methyl-4-p-toluenesulfonyl-2-butene)-6-methyl-2,3,4, 5-tetramethoxybenzene (4) is the key intermediate in the synthesis of coenzyme Q10via a coupling reaction with solanesyl bromide. In this paper, we report a simple and effective synthesis of
