Reaction Steps
A mixture of 3-(3-furyl)-2-propynyl alcohol (1.45 g, 0.0118 mol), DMAP (1 mg), TEA (2.46 ml, 0.017 mol), and acetic anhydride (1.6 ml, 0.017 mol) in 25 ml of methylene chloride was stirred for 1 hour and the mixture was poured into cold 1 N HCl solution. The mixture was extracted with ether (3×50 ml), the organic layer was dried over sodium sulfate and concentrated in vacuo. The residue was purified by silica column chromatography (hexane/ether, 2:1) to afford 1.44 g (57.5%) of 3-(3-acetyloxy-1-propynyl)furan as a clear oil.
