Liu, Gang; Li, Anqi; Qin, Xueyuan; Han, Zhengyu; Dong, Xiu-Qin; Zhang, Xumu published an article about the compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8,SMILESS:[F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10 ).SDS of cas: 36620-11-8. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:36620-11-8) through the article.
Rh/bisphosphine-thiourea ligand (ZhaoPhos)-catalyzed asym. hydrogenation of (Z)-β-substituted-β-boryl-α,β-unsaturated esters was successfully developed, furnishing a variety of chiral β-borylated carboxylic esters with high yields and excellent enantioselectivities (up to 99% yield and >99% ee). The gram-scale asym. hydrogenation was performed efficiently in the presence of only 0.05 mol% (S/C = 2000) catalyst loading with full conversion, 99% yield and 99% ee. Moreover, the hydrogenation product was easily converted to other versatile synthetic intermediates, such as Me (S)-3-hydroxy-3-phenylpropanoate and Me (S)-3-(furan-2-yl)-3-phenylpropanoate.
