hydroformylation of internal alkenes. We report here on a new class of phosphabarrelene/rhodium catalysts 2 that display very high activity towards hydroformylation of internal alkenes with an unusually low tendency towards alkene isomerization. Preparation of new phosphabarrelene ligands, studies of their coordination properties, as well as results obtained in the rhodium-catalyzed hydroformylation of cyclic

A novel class of compounds of the general formula (I), their use in therapy, pharmaceutical compositions comprising the compounds, as well as their use in the manufacture of medicaments are described. The present compounds modulate the activity of 11 β-hydroxy-Steroid dehydrogenase type 1 (11 βHSD1 ) and are accordingly useful in the treatment of diseases in which such a modulation is beneficial, e.g. the metabolic syndrome.
