Synthesis and Structure of [4.5.5.5]Fenestranes ( = tetracyclo[5.4.1.04, 12.09, 12]dodecanes)

The preparation and the X‐ray structure analysis of cis, trans, cis, cis‐10‐hydroxy‐[4.5.5.5]fenestrane‐1‐methanol (8b) is reported. The measured bond angles and bond lengths of the central C(C)4 fragment are better reproduced by calculations with the AM 1 than by the MNDO method.
