An improved method for the synthesis of tethered ruthenium(II) complexes of monosulfonylated diamines is described, together with their application to the hydrogenation of ketones and aldehydes. The complexes were applied directly, in their chloride form, to asymmetric ketone hydrogenation, to give products in excess of 99% ee in the best cases, using 30 bar of hydrogen at 60 C, and to the selective reduction of aldehydes over other functional groups.

Herein, we report the successful transformation of a 1st generation Grubbs metathesis catalyst into an asymmetric transfer hydrogenation (ATH) catalyst. Upon addition of a chiral amine ligand, an alcohol and a base, the 1st generation Hoveyda-Grubbs catalyst (HG-I) was found to promote the enantioselective reduction of acetophenone to 1-phenylethanol. After optimizing the order of addition and the reaction conditions, the substrate scope was assessed leading to enantiomeric excesses up to 97% ee. NMR experiments were run in order to get information about the in situ-generated ATH catalyst. Furthermore, the possibility to perform olefin metathesis and ketone transfer hydrogenation sequentially in one pot was demonstrated, and the first tandem olefin metathesis-ketone asymmetric transfer hydrogenation was carried out.

Efficient asymmetric transfer hydrogenation of N-sulfonylimines on water

An efficient and green approach for synthesis of optically active amines was developed via asymmetric transfer hydrogenation of N-sulfonyl ketimines catalyzed by the chiral and lipophilic rhodium-amido complex on water. Higher reactivity and enantioselectivity were observed on the hydrogenation of the solid substrate in an aqueous suspension compared to organic homogeneous phases. In the heterogeneous aqueous reaction, the reactivity depends on stirring speed and the recrystallized conditions of the solid substrate.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 144222-34-4, you can also check out more blogs about144222-34-4

PROCESS FOR PRODUCING OPTICALLY ACTIVE ALCOHOL IN THE PRESENCE OF RHODIUM, A CHIRAL FERROCENYLDIPHOSPHINE AND AN OPTICALLY ACTIVE DIAMINE

A novel process for producing optically active alcohols through asymmetric hydrogenation of prochiral carbonyl compounds allows high-yield, industrially favorable production of an optically active alcohol at a high enantiomeric excess. The process is charaterized in that the asymmetric hydrogenation is carried out in the absence of a base and in the presence of a rhodium complex or a salt thereof; an optically active ferrocenyl diphosphine; and an optically active diamine.
