A powerful inhibitor of TNF-α production, vialinin A, was synthesized from sesamol through a series of reactions involving double Suzuki-Miyaura coupling, 2,3-dichloro-5,6-dicyano-1,4-benzoquino (DDQ) mediated de-methoxymethylation and oxidative removal of methylene acetal by lead tetraacetate. The synthetic method also made it possible to prepare a related compound, terrestrin B.
通过一系列反应,包括双铃木-宫浦偶联、2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)介导的脱甲氧基甲基化和四乙酸铅氧化脱亚甲基乙缩醛,从芝麻酚合成了一种强效的 TNF-α 生成抑制剂--vialinin A。这种合成方法还可以制备一种相关化合物--terrestrin B。
