摘要：

Strained cis,cis,cis,trans-tribenzo[5.5.5.6]fenestranes are accessible in good yield by two-fold cyclodehydration of cis-2,6-diphenylspiro [cyclohexane- 1,2'-indane]-1', 3'-diols and the particularly high acidity of their 'inverted' benzylic bridgehead C-H bonds, causing facile epimerization to the more stable all-cis-tribenzo[5.5.5.6]fenestranes, is shown.
