Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 221012-82-4, is researched, Molecular C38H34N2O4P2, about Asymmetric hydrogenation of quinolines with recyclable and air-stable iridium catalyst systems, the main research direction is quinoline asym hydrogenation recyclable iridium catalyst; tetrahydroquinoline alkyl asym synthesis.Category: quinoxaline.
The iridium complex-catalyzed asym. hydrogenation of quinolines in a poly(ethylene glycol) di-Me ether (DMPEG)/hexane biphasic system was studied. Catalysts with C2-sym. ligands such as Xyl-P-Phos, Cl-MeO-BIPHEP, SYNPHOS, and DifluorPhos are highly effective for this type of reaction. Most of the catalysts tested can be retained in DMPEG (Mn = 500), and the asym. hydrogenation of various quinoline substrates can be carried out in DMPEG/hexane biphasic system with up to 92% ee. The catalysts and the products can be separated via simple phase separation, and the reactivity/stereoselectivity of the catalysts can be retained for at least three reaction cycles.
This literature about this compound(221012-82-4)Category: quinoxalinehas given us a lot of inspiration, and I hope that the research on this compound((R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine) can be further advanced. Maybe we can get more compounds in a similar way.
