Name is [1,1′-Binaphthalene]-2,2′-diol, as a common heterocyclic compound, it belongs to chiral-catalyst compound, and cas is 602-09-5, its synthesis route is as follows.,602-09-5
5.73 g (20 mmol) of (1,1?-binaphthalene)-2,2?-diol and 4.10 g (20 mmol) of p-TsOH were dissolved in 150 mL of toluene, and then stirred at about 100 C. for about 12 hours. The resulting product was cooled down to room temperature, and an aqueous potassium carbonate solution was added thereto, followed by extraction three times with 60 mL of ethyl acetate. An organic layer was collected from the resulting product and dried using magnesium sulfate. After evaporating the solvent from the resulting product, the residue was separated and purified using silica gel column chromatography to obtain 3.76 g (Yield: 70%) of Intermediate I-1. This compound was identified using liquid chromatography-mass spectrometry (LC-MS). (0315) C20H12O: M+1 268.3
With the complex challenges of chemical substances, we look forward to future research findings about [1,1′-Binaphthalene]-2,2′-diol
