602-09-5, [1,1′-Binaphthalene]-2,2′-diol is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of 5.73 g (20 mmol) of (1,1′-binaphthyl) -2,2′-diol and 4.10 g (20 mmol) of p-TsOH were dissolved in 150 mL of toluene,The solution was stirred at 100 & lt; 0 & gt; C for 12 hours.The reaction solution was cooled to room temperature,Adding a potassium carbonate solution thereto,The organic layer was extracted three times by using 60 mL of ethyl acetate.The organic layer thus collected was dried with magnesium sulfate,The residue obtained after the solvent was evaporated from the silica gel column chromatography was used to separate and purify the residue,To obtain 3.76 g of intermediate I-1 (yield: 70%).The compounds thus produced were determined by using liquid chromatography-mass spectrometry (LC-MS)., 602-09-5
As the paragraph descriping shows that 602-09-5 is playing an increasingly important role.
