The synthesis of a tricyclic substructure of solanoeclepin A is described. The key step involves an intramolecular [2+2] photocycloaddition between a dioxinone and a tetrasubstituted bicyclic alkene providing the strained bicyclo[2.1.1]hexane moiety.
描述了 solanoeclepin A 的
三环亚结构的合成。关键步骤涉及二恶英酮和四取代双环烯烃之间的分子内 [2+2] 光环加成反应,从而提供应变的双环 [2.1.1] 己烷部分。
