One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, 18531-94-7, such as the rate of change in the concentration of reactants or products with time.In a article, authors is Monguchi, Daiki, mentioned the application of 18531-94-7, Name is (R)-[1,1′-Binaphthalene]-2,2′-diol, molecular formula is C20H14O2
Discrimination of carbonyl groups of meso-alpha-diketones with Horner-Wadsworth-Emmons reagent of chiral binaphthyl esters
Asymmetric Horner-Wadsworth-Emmons reactions of selected meso-alpha-dicarbonyl compounds with chiral phosphonate reagents, which possessed axially dissymmetric 1,1?-bi-2- or 8-naphthol at the carboxylate moiety as a chiral auxiliary, were examined. The reactions proceeded smoothly with good chemical yields as well as with high diastereoselectivities. Z-olefins were preferentially formed, and it was found that the free hydroxy group at the 2?- or 8?-position on the naphthalene ring plays a crucial role in the high diastereoselectivity, probably due to a complex-induced proximity effect. Mechanistic considerations are also described.
