Ruthenium-Catalyzed Enantioselective Hydrogenation of 1,8-Naphthyridine Derivatives
The first asymmetric hydrogenation of 2,7-disubstituted 1,3-naphthyridines catalyzed by chiral cationic ruthenium diamine complexes has been developed. A wide range of U-naphthyridine derivatives were effectively hydro-genated to give 1,2,3,4-tetrahydro-1,8-naphthyridines with up to 99% ee and full conversions. The method provides a practical and facile approach to the preparation of valuable chiral heterocyclic building blocks and useful motifs for a new kind of P,N-ligand.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 91-76-9 help many people in the next few years. Recommanded Product: 91-76-9.
