Synthesis of β,β-Difluorohomoallylic Alcohols

Typical Procedure:
Under an argon atmosphere, TBAF (1.0 M in THF, 1.5 mL, 1.5 mmol) is added into a suspension of flame-dried MS4Å (1.0 g) in THF (4.0 mL) and the mixture is stirred at room temperature for 2.0 h. Then the mixture is cooled at -20 °C and a solution of ethyl 4,4-difluoro-3-(triethylsilyl)but-3-enoate (265 mg, 1.0 mmol) and benzaldehyde (204 µL, 2.0 mmol) is added to the mixture over 1.0 h at -20 °C. After stirring the mixture for
1 h at the same temperature, the whole is poured into aqueous 10% HCl, extracted with Et2O and the organic layer is dried with anhydrous MgSO4. After evaporation of the solvent, the residue is purified by column chromatography (SiO2, EtOAc : hexane) to give the desired product.
