Use | 3-tert-butylphenol is mainly used as a chiral intermediate in organic synthesis and medicinal chemistry, it can be used for the synthesis of drug molecular fragrance. In the conversion of organic synthesis, the phenolic hydroxyl group in 3-tert-butylphenol has a certain acidity, and the corresponding phenol ether products can be obtained by the reaction of phenol oxygen anion and alkyl halide under alkaline conditions. In addition, the phenolic hydroxyl groups can also be converted into the corresponding triflates, which can participate in the corresponding coupling reactions by virtue of their ready-to-leave properties. |
synthetic method | methyl trifluoromethanesulfonate (0.88mmol) A solution of 2-(3-(pentan-3-yl) phenoxy) pyridine in dry toluene was added and the solution was stirred at 100 ° C. For 2 hours under an N atmosphere. The reaction mixture was cooled to ambient temperature, the solvent was evaporated under vacuum, the crude was dissolved in dry methanol and a solution of sodium metal (12mmol) in dry methanol was added under N2 atmosphere, the reaction mixture was heated to reflux for 15 minutes and then cooled to room temperature. After completion of the reaction, the solvent was evaporated under vacuum and water (70 ml) was added. The reaction mixture was extracted with ethyl acetate (50ml x 3) and the combined organic layers were dried over anhydrous Na2SO4, the residue was purified by column chromatography on silica gel (PE/EtOAc 6:1 as eluent) by concentrating the solution in vacuo to give 3-tert-butylphenol.
