SINOPSIS

Asymmetric heterogeneous hydrogenation of the carbonyl group is one of the most important reactions for development of new chiral molecules. This study involves the asymmetric hydrogenation of α-ketoesters using a Pt/graphene support–based heterogeneous catalytic system and cinchonine as a chiral modifier. The catalyst produces high enantioselectivity (> 96.8%) and conversion (99.8%). Recyclability of the catalyst is tested for up to five cycles, and sustainable catalytic activity is found.
