1-(3,4,5-Trimethoxyphenyl)-2-propyn-1-ol → 1-(3,4,5-Trimethoxyphenyl)prop-2-yn-1-one

참여 물질

반응 단계

To a stirred solution of 1-(3,4,5-trimethoxyphenyl)prop-2-yn-1-ol (100 mg, 0.44 mmol) in acetone (10 mL), aqueous Jones reagent was added dropwise at 0° C. until the red color persisted. The reaction mixture was quenched by 2-propanol, and the precipitate was were removed by filtered through Celite. The filtrate was diluted with EtOAc, washed several times with a saturated aqueous NaHCO3 solution, water and brine, dried over MgSO4, and concentrated to give crude product, which was purified by flash chromatography eluting with EtOAc/n-hexane (1:4) to afford 1-(3,4,5-trimethoxyphenyl)prop-2-yn-1-one as a colorless oil (74 mg, 75%).
