Kinetische Enantiomerendifferenzierung bei der katalytischen Hydrierung nicht funktionalisierter Terpenolefine mit chiral modifizierten Rutheniumclustern

Article abstract of DOI:10.1016/0022-328X(91)86297-4

The catalytic hydrogenation of the racemic mixtures of α-pinene and of camphene using chirally modified ruthenium clusters leads with high diastereoselectivity to the cis-hydrogenation products.Because of the different activity of the chiral catalyst towards the enantiomers of the racemates a double stereodifferentation is achieved resulting in a kinetic resolution of the enantiomers.The enantioselectivity observed varies from 2 to 65percent.
