Among these, a “broken” dibenzo,(naphtho-d,e)[5.6.5]fenestrane, 9, and two isomeric benzo,di(naphtho-a)[6.5.5.5]fenestrane ketones, 23 and 24, were obtained in good yields by using the two-fold cyclodehydration route via the corresponding (spiro-) 1,3-indandiols. Attempts to prepare fenestranes that contain more than one six-membered ring failed.
首次描述了几种
萘代芳构的
芬太尼衍
生物16和20–26的合成。在这些当中,“破碎”二苯并(
萘d,ë)[5.6.5]窗烷,9,和两种异构苯并,二(
萘一个窗烷酮,)[6.5.5.5] 23和24,得到通过使用两倍的环脱
水途径,通过相应的(螺-)1,3-
茚满二醇,可得到良好的收率。尝试准备包含多个六元环的芬内酯失败。
