As a common heterocyclic compound, it belongs to chiral-catalyst compound, name is Benzo-18-crown 6-Ether, and cas is 14098-24-9, its synthesis route is as follows.,14098-24-9
General procedure: The carbonyl substrate (0.1 g) is dissolved in 1-2 mL of anhydrous CHCl3 and 2.0 equiv of a benzocrown ether is added to the solution. To this mixture, CF3SO3H (8.0 equiv; H2SO4 may be used in some cases) is added dropwise with stirring. The reaction is stirred at room temperature for at least 2 h, after which, the mixture is poured over several grams of ice. The resulting solution is extracted three times with CHCl3. The organic phase is subsequently washed three times with water and dried over MgSO4 solution. Removal of the solvent provides the product.
With the complex challenges of chemical substances, we look forward to future research findings about 14098-24-9,belong chiral-catalyst compound
