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.Category: quinuclidine. The article 《Stereocontrol in the synthesis of cyclic amino acids: A new ligand for directed hydrogenation through hydrogen bonding》 in relation to this compound, is published in Organic & Biomolecular Chemistry. Let’s take a look at the latest research on this compound (cas:36620-11-8).
A system for the directed hydrogenation of nitrogen heterocycles is described in which hydrogen is delivered cis to a hydroxymethyl group by a rhodium catalyst with a simple phosphine ligand. The chem. is applied to the synthesis of the hygric acid moiety of Lincomycin and the pipecolic acid moiety of Argatroban. A series of control experiments indicate that the stereoselectivity is a result of a combination of both coordination and hydrogen bonding.
As far as I know, this compound(36620-11-8)Application In Synthesis of Bis(norbornadiene)rhodium (I) tetrafluoroborate can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
