Reaction Steps

(E)-4-(2,2-dimethylpropoxy)but-3-en-2-one (14 g, 90 mmol) and triethylamine (10 g, 101 mmol) were combined in ethyl ether (200 mL). Trimethylsilyl trifluoromethanesulfonate (20 g, 90 mmol) (Aldrich) in carbon tetrachloride (30 mL) was added at −5° C. over 0.5 hr. This was stirred for 0.5 hr at 0° C. This was poured into cold 5% sodium bicarbonate (50 mL) and the organics were extracted into hexane. This was washed with saturated aqueous sodium chloride, dried (MgSO4), and evaporated to give 21 g of [(E)-3-(2,2-dimethylpropoxy)-1-methylene-allyloxy]trimethylsilane.
