levulinic acid and its esters. A tartaric acid-NaBr-modified nickel catalyst produced the optically-active γ-valerolactone with a 60% enantiomeric excess (ee), almost quantitative conversion and chemoselectivity. The synthesis of the optically-active γ-valerolactone using the enantio-selective heterogeneous catalyst would be promising for the large-scale industrial production from levulinic acid and its
