Hydrogenolysis of Small Cycloalkanes, XIII - Hydrogenation of Homucubane Derivatives

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.
