Allyl bromide → 1,3-Benzodioxole, 5-(2-propenyloxy)-

Participants

Reaction Steps

Allyl bromide (1.75 g., 14 mmol) was added to a solution of sesamol (2.0 g, 14 mmol) that had been dissolved in 50 ml of dry acetone, followed by addition of powdered potassium carbonate (2.4 g, 17 mmol) and the resulting cloudy solution was refluxed for 18 h. The solution was cooled and the solvent removed in vacuo. The remaining suspension was extracted into ether and the organic layer was washed with water (1×25 ml ), brine solution (1×25 ml ), and dried over MgSO4. Concentration of solvent yielded 2.4 g (94%) of a pale yellow oil which was used in the next step with no further purification.
