摘要:以2,3,4,5-四甲氧基甲苯为原料,经溴化、生成格氏试剂后在碘化亚铜存在下与(E)-4-氯-2-甲基-1-苯磺酰基-2-丁烯缩合得到合成辅酶Q10的关键中间体6-(E-3'-甲基-4'-苯磺酰基-2'-丁烯基)-2,3,4,5-四甲氧基甲苯.此中间体与茄尼基溴缩合、脱砜基化反应和氧化三步反应,最终制得标题化合物辅酶Q10,以2,3,4,5-四甲氧基甲苯计总收率达31.3%.
2,3,4,5-Tetramethoxytoluene was brominated to prepare 6-bromo-2,3,4,5-tetramethoxytoluene whose Grignard reagent was condensed with (E)-4-cholro-2-methyl-1-phenylsulfonyl-2-butene in the presence of cuprous iodide to obtain the intermediate 6-(E-3'-methyl-4'-phenylsulfonyl-2'-butenyl)-2,3,4,5- tetramethoxytoluene, from which coenzyme Q10 was finally achieved via condensation with solanesyl bromide, desulfonylation and oxidation with an overall yield of 31.3% based on 2,3,4,5-tetramethoxytoluene.
