[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
under nitrogen protection,2.5 g of binaphthol was dissolved in 100 ml of tetrahydrofuran,The solution was cooled to 0 C,Then slowly add 0.88 g of sodium hydride and stir for 15 minutes.Take 1.65 ml of 98% chloromethyl ether slowly,The mixture was warmed to room temperature for 4 hours and quenched with water.Extracted with ethyl acetate, dried over anhydrous sodium sulfate,The column was purified by silica gel column to give 2.3 g of product as a 71% yield.
602-09-5 is used more and more widely, we look forward to future research findings about [1,1′-Binaphthalene]-2,2′-diol
