A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Formula: C20H16N2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 18741-85-0, Name is (R)-[1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Article, authors is Suga, Hiroyuki，once mentioned of 18741-85-0
Chiral Ni(II)-1,1?-binaphthyl-2,2?-diimine complexes were found to be effective Lewis-acid catalysts for an asymmetric 1,3-dipolar cycloaddition reaction of N-benzylideneaniline N-oxide with 3-crotonoyl-2-oxazolidinone. In the presence of molecular sieves (4 A, when the chiral N,N? -bis(2,6-dichlorobenzylidene)-1,1?-binaphthyl-2,2?-diamine (BINIM-DC) and Ni(ClO4)2·6H2O were used to prepare the catalyst, up to 81% ee of the corresponding endo-cycloadduct was obtained with endo- selectivity (87:13, and up to 96:4). The use of N,N?-bis(3-chloro-substituted 2-hydroxybenzylidene) derivatives as ligands under similar conditions showed high exo-selecfivity (up to 95:5) with moderate enantioselectivity. Although almost no diastereoselectivity was observed, endo- and exo-cycloadducts were obtained with promising levels of enantioselectivity (up to > 98%) in the presence of catalysts, which were prepared from chiral BINIM-DC, NiBr2, and AgBF4, AgSbF6, or AgPF6.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18741-85-0, help many people in the next few years.Formula: C20H16N2
