Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 36620-11-8, is researched, SMILESS is [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10, Molecular C14H8BF4RhJournal, Article, Research Support, Non-U.S. Gov’t, Review, Angewandte Chemie, International Edition called Stereoelectronic Effects in Ligand Design: Enantioselective Rhodium-Catalyzed Hydrogenation of Aliphatic Cyclic Tetrasubstituted Enamides and Concise Synthesis of (R)-Tofacitinib, Author is Li, Chengxi; Wan, Feng; Chen, Yuan; Peng, Henian; Tang, Wenjun; Yu, Shu; McWilliams, J. Christopher; Mustakis, Jason; Samp, Lacey; Maguire, Robert J., the main research direction is carbocyclic heterocyclic amine enantioselective synthesis ligand catalyzed hydrogenation enamide; Tofacitinib enantioselective synthesis Rhodium bisphosphorus ligand catalyzed hydrogenation enamide; P ligands; asymmetric hydrogenation; enamides; stereoelectronic effects; tofacitinib.Formula: C14H8BF4Rh.
We herein report the development of a conformationally defined, electron-rich, C2-sym., P-chiral bisphosphorus ligand, ArcPhos, by taking advantage of stereoelectronic effects in ligand design. With the Rh-ArcPhos catalyst, excellent enantioselectivities and unprecedentedly high turnovers (TON up to 10,000) were achieved in the asym. hydrogenation of aliphatic carbocyclic and heterocyclic tetrasubstituted enamides, to generate a series of chiral cis-2-alkyl-substituted carbocyclic and heterocyclic amine derivatives in excellent enantiomeric ratios. This method also enabled an efficient and practical synthesis of the Janus kinase inhibitor (R)-tofacitinib.
In some applications, this compound(36620-11-8)Formula: C14H8BF4Rh is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
