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
(¡À)-BINOL (24.9 g, 86.9 mmol), 1-bromobutane (25.0 g, 182.5 mmol), potassium carbonate (36.0 g, 260.7 mmol) was added to a solution of DMAc (250 mL), and the mixture was stirred at 90 C. for 10 hours for reaction. Further, potassium carbonate (15.0 g, 108.5 mmol), 1-Bromobutane (11.5 g, 83.9 mmol) was added, the mixture was stirred at the same temperature for 12 hours and reacted. After cooling to room temperature, toluene and ion exchanged water were added, the organic layer was washed twice with ion exchanged water, and the solvent was distilled off under reduced pressure. Methanol was added to the concentrate, the solid content was dispersed, filtered, dried under reduced pressure at 40 C., Intermediate 172A (32.1 g, 92.7%) was obtained as a cream colored solid.
With the complex challenges of chemical substances, we look forward to future research findings about [1,1′-Binaphthalene]-2,2′-diol
