Pagodane is an organic compound with formula C20H20 whose carbon skeleton was said to resemble a pagoda, hence the name.

In particular, the basic compound C20H20 has those carbons connected by four methylene bridges (m=n=p=q=1), and its name within that family is therefore [1.1.1.1]pagodane.

Prinzbach remarked that "the obvious need for [the short name 'pagodane'] can be readily understood in view of the von Baeyer/IUPAC and Chemical Abstracts nomenclature", undecacyclo[9.9.0.01,5.02,12.02,18.03,7.06,10.08,12.011,15.013,17.016,20]icosane.

While fewer steps and higher yield look attractive at first sight, this approach had to be given up due to high cost and restricted availability of the dioxide.

[4][5] These dications were the first examples to show the phenomenon of σ-bishomoaromaticity which was subsequently studied by the Prinzbach group to great length.
