Reaction Steps

Sodium hydride (1.32 g, 55 mmol) was added to a solution of 2,2-dimethyl-1,3-dioxolane-4-methanol (Aldrich) in THF (60 mL), and the resulting mixture was heated at reflux for 90 min then cooled to 0° C. Tetrabutylammonium iodide (370 mg), and propargyl bromide (80% in toluene, 6.22 mL, 50 mmol) (Aldrich) were added successively. After stirring for 150 min. at room temperature, 20 mL water was added and the THF was evaporated in vacuo. The aqueous layer was then extracted with diethyl ether (4×50 mL), and the combined organic layers were dried over magnesium sulfate and concentrated in vacuo to yield rac-3-[(2,2-dimethyl-1,3-dioxolan-4-yl)methoxyl-1-propyne.
