The hydrogenation of endo-6-methylenebicyclo[2,2,2]octan-2-ol catalysed by a range of rhodium and iridiumcomplexes has been investigated. Unlike the corresponding exo-alcohol, reduction is highly stereoselective leading to 95 – 99.7% of endo-exo-6-methylbicyclo[2,2,2]octan-2-ol. Selectivity is much less pronounced for the corresponding methyl ether. Rhodium catalysts promote a competitive isomerisation
