An improved route to coenzyme Q10 (1) starting from commercially available coenzyme Q1 is described. The key steps in this synthesis are the SeO2-mediated oxidation of the protected isoprenylhydroquinone 3 into the (E)-allyl alcohol 5 without the formation of undesired stereoisomer and the one-pot reductive elimination of the phenylsulfonyl and dibenzyl groups in 7 by using naphthalenyllithium.

Physiologically active polyisopreoidquinones, ubiquinone-10 (coenzyme Q10), phylloquinone (vitamin K1), and menaquinone-4 (vitamin K2(20)) were synthesized by a chain-extending method utilizing protected hydroquinones with the omega-hydroxyprenyl or omega-hydroxygeranyl side chain.Conditions for reductive desulfurization subsequent to allylic homologation was investigated. Keywords - polyisoprenoidquinone synthesis; ubiquinone-10; phylloquinone; menaquinone-4; chain-extending method; sulfone coupling; reductive desulfurization
