[1,1′-Binaphthalene]-2,2′-diol, cas is 602-09-5, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,602-09-5
General procedure: Separately, each of the dihydroxy-substituents, catechol (a), 2,3-dihyroxynaphthalene (b), 2,2′-dihydroxy-1,1′-bisnaphthalene (c) (50 mmol), and NaOH (0.12 mol) were dissolved in 20-25 ml ethanol and 2-chloroethanol (0.12 mol) was added to this solution dropwise over 15 min. After refluxing the reaction mixture for 20 h, the resulting solid was separated by filtration. Ethanol was evaporated in vacuo and the resulting oily product was dissolved in 200 ml chloroform. The chloroform solution was washed with 3% NaOH and then with distilled water until the pH reached neutrality.
As the rapid development of chemical substances, we look forward to future research findings about 602-09-5
