实验步骤: To a solution of (E)-3-(4-isopropylphenyl)-2-propen-1-ol (10.5 g, 59.6 mmol) in isopropyl ether (100 ml) was added under ice cooling phosphorus tribromide (10.7 g, 39.7 mmol) and the resulting mixture was stirred at room temperature for 30 minutes. Water was added into the reaction solution and the product was extracted with isopropyl ether. The organic layer was washed with water and an aqueous saturated solution of sodium hydrogen carbonate, dried on magnesium sulfate, filtered, and then concentrated under reduced pressure to obtain 10.2 g (72% yield) of the oily title compound. the product was extracted with isopropyl ether The organic layer was washed with water an aqueous saturated solution of sodium hydrogen carbonate, dried on magnesium sulfate filtered concentrated under reduced pressure

实验步骤: To a suspension of ethyl (E)-3-(4-isopropylphenyl)-2-propenoate (20.0 g, 91.6 mmol) in tetrahydrofuran (200 ml) was added in four portions at −40° C. for 30 minutes lithium aluminum hydride (2.61 g, 68.7 mmol) and the resulting mixture was stirred at the same temperature for 30 minutes. Water was added into the reaction solution and the product was extracted twice with ethyl acetate. The combined extracts were washed with water, dried on magnesium sulfate, and then concentrated under reduced pressure. The residue was subjected to column chromatography on silica gel (hexane-ethyl acetate 8:1) to obtain 10.5 g (65% yield) of the oily title compound. the product was extracted twice with ethyl acetate The combined extracts were washed with water dried on magnesium sulfate concentrated under reduced pressure
