The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, molecular formula is C20H13O4P.

An organocatalytic arylation of 3-indolylmethanols has been established via chemo- and regiospecific C6-functionalization of 2,3-disubstituted indoles, leading to the production of bisindolyloxindoles containing an all-carbon quaternary stereocenter in high yields (up to 99% yield). This reaction not only represents the first catalytic arylation of 3-indolylmethanols using 2,3-disubstituted indoles as aromatic nucleophiles but also serves as a good example of direct catalytic C6-functionalization of indoles, which have been scarcely investigated. Besides, this approach also provides an efficient method to access a biologically important 3,3?-disubstituted oxindole framework and a 3?,6-linked bisindole skeleton. Furthermore, the investigation of the activation mode suggested that the dual activation of an ion pair and H-bond between the substrates and the catalyst cooperatively contributed to the success of the reaction.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 39648-67-4 is helpful to your research., Quality Control of: (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide
