A practical, highly stereoselective ten-step synthesis of coenzyme Q10 (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
从商业上可获得的2,3-二甲氧基-5-甲基苯醌(方案)开始,已经完成了实用的,高度立体选择性的辅酶Q 10(1)的十步合成(总产率约为28%)。通过芳族体系3与环氧乙烷的偶联反应,随后的Swern氧化和Wittig烯烃化,实现具有(E)-构型的第一侧链异戊烯基(化合物6)的引入。用萘二甲酸钠在THF中选择性除去砜9中的甲苯磺酰基(Ts),得到1。
