Madec, J.; Pfister, X.; Phansavath, P.; Ratovelomanana-Vidal, V.; Genet, J.-P. published the article 《Asymmetric hydrogenation reactions using a practical in situ generation of chiral ruthenium-diphosphine catalysts from anhydrous RuCl3》. Keywords: asym hydrogenation catalyst ruthenium diphosphine.They researched the compound: (S)-Methyl 3-hydroxybutanoate( cas:53562-86-0 ).Name: (S)-Methyl 3-hydroxybutanoate. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:53562-86-0) here.
A very simple in situ preparation of chiral ruthenium-diphosphine catalysts from anhydrous RuCl3 is reported. Prochiral C:O and C:C bonds have been reduced with high enantioselectivities via ruthenium-catalyzed hydrogenation.
