  Pentacyclic Compounds by Samarium Diiodide‐Induced Cascade Cyclizations of Naphthyl‐Substituted 1,3‐Diones

  摘要：

  AbstractTreatment of naphthyl‐substituted cyclopentane‐1,3‐diones with the samarium diiodide‐ hexamethylphosphoramide (HMPA) complex in the presence of tert‐butyl alcohol provided the expected tetracyclic diols with steroid‐like structures. Surprisingly, reactions without the proton source led to the efficient formation of a new pentacyclic diol. In this case the toxic additive HMPA could be substituted by a combination of lithium bromide (in situ generation of samarium dibromide) and N,N‐dimethylimidazolidone. The styrene‐like alkene moiety of this product was used to prepare an ensemble of highly substituted pentacyclic steroid‐like compounds.
