▎ 摘　　要

NOVELTY - Graphene adsorption multi-component chiral catalyst 2a/graphene compound (I) is new. USE - (I) is useful in asymmetric hydrogenation of dehydrogenated amino acid derivatives (claimed). ADVANTAGE - (I): exhibits excellent asymmetry induction effect, more than 99% conversion rate and 96% enantiomeric excess; can be recycled by simple filtration; and provides excellent reference for the development of other heterogeneous hybrid chiral catalysts based on asymmetric reactions with non-covalent interactions. DETAILED DESCRIPTION - Graphene adsorption multi-component chiral catalyst 2a/graphene compound of formula (I) is new. boxes = adsorption on graphene. INDEPENDENT CLAIMS are also included for: (1) preparation of (I); and (2) use of (I) in asymmetric hydrogenation of dehydrogenated amino acid derivatives.
