Hydrogenation of asymmetric and symmetric hexahydropyrene gives the five possible aromatic decahydropyrenes via different octahydropyrenes.From these compounds some dodecahydro- and tetradecahydro-pyrenes, the four isomers of perhydropyrene with chair conformations and five new stereoisomers with twist boat six-membered rings are obtained.The configurations of the hydrogenated pyrenes are assigned using chromatographic retention indices and mass spectrometric fragmentation in combination with force field calculations.

The treatment of metacyclophanes with aluminum chloride gave a variety of hydropyrenes as the results of dehydrogenation, cycloisomerization, and disproportionation reactions.With ethylaluminum dichloride, however, a highly selective reaction occured to give trans-trans-1,2,3,3a,4,5,9,10,10a,10b-decahydropyrene.Revised structures were presented for cis-cis- and trans-trans-decahydropyrenes based on 13C NMR and X-ray crystallographic analyses.
