Category: piperazines. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: (S)-Methyl 3-hydroxybutanoate, is researched, Molecular C5H10O3, CAS is 53562-86-0, about Synthesis of BINAP ligands with imidazole tags for highly enantioselective Ru-catalyzed asymmetric hydrogenation of β-keto esters in ionic liquid systems. Author is Jin, Xin; Kong, Fang-fang; Yang, Zhi-qiang; Cui, Fei-fei.
The imidazole-tagged BINAP ligands were synthesized and used for Ru-catalyzed asym. hydrogenation of β-keto esters in ionic liquid (IL) systems. The Ru-BINAP catalysts with the imidazolium tags show high catalytic activity and enantioselectivity, which closely parallel the performance of unmodified BINAP. The catalyst recycling experiments using [bmim]Tf2N/MeOH system demonstrated that introducing imidazolium moieties to the BINAP backbone can effectively enhance the affinity of the Ru-catalysts to the IL, reduce Ru leaching and improve catalysts stability, and after several cycles no significant loss of activity and enantioselectivity was observed
