A practical synthesis of coenzyme Q10 has been developed. The route features an improved Friedel-Crafts allylation of tetramethoxytoluene with a para-chlorobenzenesulfonyl-substituted C5 allylic chloride at 40 °C. Replacement of the methyl ether protecting groups of the para-hydroquinone by methoxymethyl groups at Q1 stage proceeded efficiently, and allowed the facile final oxidation to coenzyme Q10 to occur under mild acidic conditions. The overall yield of coenzyme Q 10 from commercially available tetramethoxytoluene reached 53 % in this improved procedure. An improved synthesis gave CoQ10 in 53 % overall yield from tetramethoxytoluene through Friedel-Crafts allylation with a para-chlorobenzenesulfonyl-substituted C5 allylic chloride and a modified oxidation procedure.

A practical, highly stereoselective ten-step synthesis of coenzyme Q 10 (1) has been accomplished (overall yield ca. 28%), starting from commercially available 2,3-dimethoxy-5-methylbenzoquinone (Scheme). The introduction of the first side-chain isoprenyl group with (E)-configuration (compound 6) was realized by means of a coupling reaction of the aromatic system 3 with oxirane, followed by Swern oxidation and Wittig olefination. The tosyl (Ts) group in the sulfone 9 was selectively removed with sodium naphthalenide in THF to afford 1.

Co-enzyme Q10 was efficiently synthesised by stereo- and regio-selective prenylation of the protected hydroquinone (2) with isoprene epoxide and solanesyl p-tolyl sulphone in a good overall yield.
