A synthetic approach to ring-D aromatic steroids, viz. 5, based on a cascade of radical-mediated cyclisations from the orthoaryl-substituted iododienynones 12 and 13, instead led to the macrocyclic ketone 16 or to the novel, bridged tricycle 17, respectively, as the major products.
环 D 芳香族类固醇的合成方法,即。图 5 基于邻芳基取代的碘二烯酮 12 和 13 的一系列自由基介导的环化反应,分别生成大环酮 16 或新型桥连三环 17 作为主要产物。
