在室温下,通过非催化Diels-Alder环加成反应实现了二聚二萜类化合物组氨酸A的不对称全合成。该合成依赖于铁催化的偶联反应来构建Z构型的三取代烯烃,铁催化的自由基级联反应生成拉布丹类型的二烯,山本阳离子多烯的环化和钯催化的Stille偶联生成托烷类型的双烯亲和分子。
Asymmetric total synthesis of the dimeric diterpenoid hispidaninA was accomplished by non-catalytic Diels-Alder cycloaddition at room temperature. The synthesis relies on iron-catalyzed coupling to construct a Z-configured trisubstituted alkene, an iron-catalyzed radical cascade to generate a labdane-type diene, and both Yamamoto cationic polyene cyclization and palladium-catalyzed Stille coupling to generate a totarane-type dienophile.
