One pot selective hydrogenation and dynamic kinetic resolution over Cu/Al2O3: A way to (-)-menthol starting from low value mint oils

One pot selective hydrogenation and dynamic kinetic resolution over Cu/Al2O3: A way to (-)-menthol starting from low value mint oils

One pot selective hydrogenation of (+)-pulegone to menthols can be obtained by using a heterogeneous copper catalyst under very mild experimental conditions. Stereoselectivity to (-)-menthol can be improved from 23 to 41% by exploiting a dynamic kinetic resolution over the same catalyst in a one pot...

Zusammenfassung:One pot selective hydrogenation of (+)-pulegone to menthols can be obtained by using a heterogeneous copper catalyst under very mild experimental conditions. Stereoselectivity to (-)-menthol can be improved from 23 to 41% by exploiting a dynamic kinetic resolution over the same catalyst in a one pot-one step process.
