The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate(SMILESS: [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10,cas:36620-11-8) is researched.Recommanded Product: Bis(norbornadiene)rhodium (I) tetrafluoroborate. The article 《Highly Regio- and Enantioselective Hydrogenation of Conjugated α-Substituted Dienoic Acids》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:36620-11-8).
Highly regio- and enantioselective hydrogenation of conjugated α-substituted dienoic acids was realized for the first time using Trifer-Rh complex, providing a straightforward method for the synthesis of chiral α-substituted γ,δ-unsaturated acids. DFT calculations revealed N+H-O hydrogen bonding interaction is formed to stabilize the transition state and the coordination of 4,5-double bond to Rh(III) center would facilitate the reductive elimination process. This hydrogenation provided a gram-scale synthesis of the precursor of sacubitril.
