Catalytic Conversion of Biomass-Derived Carbohydrates into γ-Valerolactone without Using an External H2Supply

Simplified procedure: A new catalytic route was developed for the conversion of biomass carbohydrates into γ-valerolactone (GVL) without using an external H2 supply. A model experiment with glucose provided γ-valerolactone in 48 % yield. An interesting positive effect of CO2 on the Ru-catalyzed hydrogenation was also observed. py=pyridine.
