Reaction Steps

Trimethyl-(1-methylene-tetradecyloxy)-silane (176 mg, 0.6 mmol) and the enone 21 (176 mg, 0.3 mmol) are dissolved in 2 mL of anhydrous THF and the solution is cooled down to −78° C. Two drops of tetrabutylammonium fluoride (1 M in THF) are injected. The mixture is stirred for 1 h at this temperature, then the solution is left to return to ambient temperature under stirring. After the addition of water and extraction with ethyl acetate, the product is dried and the solvent is evaporated off. The residue is purified by flash chromatography in order to produce compound 22.
