The synthesis of (±)-epiisopodophyllotoxin commencing with 6-bromopiperonal dimethyl acetal is described. The carbon skeleton of isoepipodophyllotoxin was assembled via a Diels–Alder reaction between the hydroxyquinodimethane generated photochemically from 6-(3′,4′,5′-trimethoxybenzyl)-piperonal, obtained from the bromoacetal above, and dimethyl fumarate. This Diels–Alder adduct was converted in five
描述了从 6-溴胡椒醛二甲基乙缩醛开始的 (±)-表鬼臼毒素的合成。异鬼臼毒的碳骨架是通过从上述溴缩醛获得的 6-(3',4',5'-三甲氧基苄基)-胡椒醛和富马酸二甲酯以光化学方式产生的羟基醌二甲烷之间的 Diels-Alder 反应组装的。该 Diels-Alder 加合物分五步转化为标题化合物。七个步骤的总产率为 15%。
