Reaction Steps

1.20 mL of diethyl ether was added to 3-(2-trimethylsilanylmethyl-buta-2,3-dienyl)-isochroman-1-ol (78 mg, 0.27 mmol) under nitrogen atmosphere. While stirring at −78° C., TMSOTf (49 μL, 0.27 mmol) was added. While stirring the reaction mixture, the reaction temperature was slowly increased to room temperature for 3 hours. The reaction mixture was stirred at room temperature for 30 minutes. After the reaction was completed, H2O was added. After stirring for about 5 minutes, the reaction mixture was diluted with EtOAc and washed with water and saturated brine. The organic layer was separated from the reaction mixture and dried with anhydrous MgSO4. The solvent was removed under reduced pressure and the remaining material was purified with column chromatography (EtOAc/n-hexane=⅙) to obtain 42 mg of the product (78%).
