An Ag-catalyzed radical cascade bicyclization/aromatization of C-linked 1,7-enynes with 1,3-dicarbonyls has been achieved, providing a step- and atom-economy approach for the construction of 2,3-dihydro-1H-cyclopenta[a]naphthalenes, an important structural scaffold existed in biologically active compounds. From this transformation, structurally diverse 2,3-dihydro-1H-cyclopenta[a]naphthalenes were
已经实现了银催化自由基级联双环化/芳构化的C-连接的 1,7-烯炔与 1,3-二羰基,为构建 2,3-二氢-1 H-提供了一步和原子经济的方法-环戊二烯[ a ]萘,一种重要的结构支架,存在于生物活性化合物中。通过这种转化,以中等至良好的产率和高区域选择性获得了结构多样的 2,3-二氢-1 H-环戊二烯 [ a ] 萘。此外,还举例说明了进一步的产品衍生化。
