Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Efficient Access to Chiral β-Borylated Carboxylic Esters via Rh-Catalyzed Hydrogenation, the main research direction is chiral beta borylated carboxylic ester preparation rhodium catalyzed hydrogenation; ZhaoPhos rhodium bisphosphine thiourea catalyzed asym hydrogenation boryl ester; beta substituted boryl unsaturated ester rhodium bisphosphine thiourea hydrogenation; borylated carboxylic ester beta chiral preparation.COA of Formula: C14H8BF4Rh.
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.
