Methanol → 6,6-Difluoro-5-methyl-5-hexenol

참여 물질

반응 단계

To 110 ml of tetrahydrofuran, 53 g (0.30 mol) of methyl 6,6-difluoro-5-methyl-5-hexenoate was dissolved, followed by adding 23 g (0.61 mmol) of sodium borohydride, heating the mixture under refluxing and slowly drop-wisely adding 50 ml of methanol. After the end of the drop-wise addition, the reaction liquid was stirred under refluxing for 1 hour, followed by cooling to room temperature, adding water and extracting with diethyl ether. The organic layer was washed with water, dilute hydrochloric acid and a saturated saline solution in this order, followed by drying over anhydrous magnesium sulfate, and concentrating under reduced pressure to obtain 36.5 g (yield: 82%) of 6,6-difluoro-5-methyl-5-hexenol.
