higher rate than its 2exo-isomer 2 to 2endo, 6endo-trimethylenenorbornane (3) as the sole product. By consequence, the hydrocarbon 2 being the next intermediate in the sequence of the adamantane rearrangement of 1 seems to be very unlikely.

ornane (2) is described. Starting from a mixture of pent-4-ynylcyclopentadienes 3 the tricyclic monosaturated key intermediate 5 was prepared by intramolecular cycloaddition (4) and subsequent regioselective reduction of the C(5), C(6) double bond. The title hydrocarbon 2 was obtained from 5 upon stereoselective hydrogenation by diimide. In addition specifically deuteriated analogues of 2 were prepared

Unexpected differences in the aluminium bromide-catalyzed rearrangement behaviour of 1,2--trimethylenenorbornane () and its 1,2--isomer () are interpreted. Isotopic labelling studies indicate that reversible abstraction of the tertiary 2- hydride in does not occur. Instead, rearrangement to is favored. The label scrambling in the final product, adamantane (), is attributed to degenerate isomerization in the
