to give benzannulated enyne-allenes for the subsequent Schmittel cascade cyclization reactions. The structures of these two 5-(1-naphthyl)-11H-benzo[b]fluorenes could be regarded as 2,2'-disubstituted 1,1'-binaphthyls with the newly constructed benzofluorenyl group serving as a naphthyl moiety.
5-(2-Methoxy-1-naphthyl)-和5-[2-(甲氧基甲基)-1-naphthyl]-11H-苯并[b]芴通过用叔丁醇钾回流处理相应的苯并环化烯二炔合成甲苯生成苯并环化的烯炔-丙二烯,用于随后的施密特级联环化反应。这两种 5-(1-萘基)-11H-苯并 [b] 芴的结构可以看作是 2,2'-二取代的 1,1'-联萘,新构建的苯并芴基作为萘基部分。
