In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 7556-37-8, name is 1-Methyl-1H-indol-4-ol, introducing its new discovery. Recommanded Product: 7556-37-8
Organocatalytic Enantioselective Friedel?Crafts Alkylation/Lactonization Reaction of Hydroxyindoles with Methyleneoxindoles
Functionalization of the indole benzene ring was achieved by using an organocatalytic enantioselective Friedel?Crafts alkylation/lactonization reaction of hydroxyindoles with a variety of substituted methyleneoxindoles. This reaction was applicable to indoles substituted with the hydroxy group at different positions of the benzene ring, and the corresponding pyrrolodihydrocoumarins were obtained in moderate to high yields (37?99%) with high stereoselectivities (up to 99% ee and >20:1 dr) in most cases. A scale-up reaction and derivatization of the representative products were also carried out to investigate the usefulness of this protocol. (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 7556-37-8 is helpful to your research. Recommanded Product: 7556-37-8
