arylacetates with 2-aryl-3-methoxymaleic anhydrides e.g. (3) gives intermediates viz (8) which can be dehydrated to -and -isomers of permethylated pulvinic acids; treatment of the latter with trimethylsilyl iodide provides the corresponding pulvinic acids e.g. gomphidic acid (1).
衍生自芳基乙酸酯的烯醇锌(例如)(6)与2-芳基-3-甲氧基马来酸酐(例如)(3)反应,得到中间体(8),可以将其脱水成全甲基化的戊二酸的-和-异构体;用三甲基甲硅烷基碘处理后者可提供相应的豆蔻酸,例如gomphidicic acid(1)。
