Electric Literature of 4687-25-6, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4687-25-6, molcular formula is C9H6O2, introducing its new discovery.
Constructing fused hydrodibenzofuran architectures bearing a tetrasubstituted stereogenic center adjacent to an O atom is extremely difficult. Here we have developed an asymmetric dearomatizative Diels?Alder reaction using novel 2-(3-vinylbenzofuran-2-yl)ethan-1-one substrates and 3-olefinic 7-azaoxindoles. The reaction proceeds via in situ generation of a HOMO-raised formal trienamine species with a chiral primary amine catalyst, producing highly complex tetrahydrodibenzo[b,d]furan derivatives with vicinal tetrasubstituted stereogenic centers in moderate yields with excellent stereoselectivity (dr>19:1, up to 98% ee). (Figure presented.).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4687-25-6 is helpful to your research. Electric Literature of 4687-25-6
