Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 53562-86-0, is researched, SMILESS is C[C@H](O)CC(OC)=O, Molecular C5H10O3Journal, Carbon called Reduced graphene oxide supported chiral Ni particles as magnetically reusable and enantioselective catalyst for asymmetric hydrogenation, Author is Ding, Chao; Wei, Weili; Sun, Hanjun; Ding, Jinhua; Ren, Jinsong; Qu, Xiaogang, the main research direction is reduced graphene oxide supported nickel magnetically reusable enantioselective catalyst; asym hydrogenation enantioselective reduced graphene oxide supported nickel.Safety of (S)-Methyl 3-hydroxybutanoate.

A reduced graphene oxide (rGO) supported chiral-modified Ni catalyst was synthesized, characterized and employed for asym. hydrogenation. The prepared hybrid catalyst could produce each enantiomer with D- or L-tartaric acid as chiral modifier and exhibited a high TOF (20160 h-1) and enantioselectivity (enantiomeric excess, 98.5%) for asym. hydrogenation of Me acetoacetate. The high catalytic activity and enantioselectivity were mainly attributed to the unique properties of the support rGO, as it had a large sp. surface area to sustain and stabilize Ni particles and its high charge carrier mobility could enable the readily transfer of electrons in the reaction process. Besides, the catalyst could also gain an enhanced reactant sorption with the support of rGO, thus achieved a greatly catalysis enhancement. The ferromagnetism of Ni made the catalyst easier for separation and reuse. The catalytic and recycling performance of the prepared chiral Ni catalyst demonstrated that rGO was indeed a promising support to improve activity, enantioselectivity and durability of catalysts, and the prepared catalysts were promising reusable heterogeneous catalysts for asym. hydrogenation.
