Two dihydro products 5a and 7a are formed by hydrogenation of homocubane (6a) with Pd-, Pt-, and Rh-catalysts.Only the unsymmetric 7a reacts further to give twistbrendane (8a).In addition, ca. 20percent brendane (11a) is obtained by hydrogenation of homocuneane (9a), which is formed from 6a by rearrangement on the catalyst.The yield of the symmetric dihydro product 5b is raised up to 40percent in the case of hydrogenation of the ethylene acetal 6b of the 9-ketone on Rh/Al2O3.With the ester 6d no 5d is obtained but 7d and 8d only.

The esters of cis-bicyclononenols, exo- and endo-brexan-5-ols, and exo-brendan-2-ol were obtained by the addition of formic, acetic, and trifluoroacetic acids to cis-bicyclonona-3,7-diene.The composition of the reaction products and its dependence on the reaction conditions were determined.A method is proposed for the separation of the bicyclic and tricyclic components.The mechanism of the transannular cyclization is discussed.
