实验步骤: To a solution of 1,3-benzenediol (8 g, 72.7 mmol) and 2-iodopropane (12 g, 70.6 mmol) in ethanol (100 mL preheated at reflux) was added a solution of KOH (83%, 5.3 g, 77.6 mmol) in water (20 mL) over a period of 30 minutes. The mixture was refluxed for 3 hours and poured into NaOH (1 N, 100 mL). The resulting mixture was extracted with ethyl acetate (3 times 50 mL) and the aqueous layer was acidified with 10% HCl to adjust the pH=5 and extracted with ethyl acetate (3 times 50 mL). The combined extracts were washed with brine (50 mL), dried and concentrated under vacuum. The residue was purified by column chromatography on silica gel (PE:EtOAc=5:1) to afford the title compound as a colourless oil (2.1 g).

实验步骤: In 10 ml of THF, 1.5 g of resorcinol was dissolved and 2.24 ml of DBU was added under ice cooling. The resultant mixture was stirred for 10 min at room temperture. To the mixture, 1.92 ml of isopropyl bromide was added and refluxed for 2 hr. The reaction mixture was neutralized with acetic acid and evaporated under reduced pressure. The evaporated residue was redissolved in ethyl acetate and washed with 5% aqueous citric acid solution and saturated aqueous sodium chloride solution, successively, and dried over anhydrous sodium sulfate. The dried solution was evaporated under reduced pressure and the residue was subjected to a silica gel column chromatography (chloroform:methanol=40:1) to give 466 mg of the title compound. refluxed for 2 hr evaporated under reduced pressure The evaporated residue was redissolved in ethyl acetate washed with 5% aqueous citric acid solution and saturated aqueous sodium chloride solution successively, and dried over anhydrous sodium sulfate The dried solution was evaporated under reduced pressure
