Hydrogenation selectivity of the Bicyclo[4.4.0]decane ring system of valencanes
Abstract
To test the selectivity of sterically hindered systems, (+)-nootkatone and derivatives were subjected to a wide variety of hydrogenation methodologies. The steric impact of the C-4 methyl substituent seems to be responsible for the inability of the system to adopt the cis-fused structure. © Georg Thieme Verlag Stuttgart New York.
