Tetrabutylammonium Fluoride → 1-Hydroxy-2-tetrahydropyranyloxy-2-(4-tert-butylphenyl)ethane

Participants

Reaction Steps

To 1-tert-butyldimethylsilyloxy-2-tetrahydropyranyloxy-2-(4-tertbutylphenyl) ethane (0.4 g, 1.01 mmol) is added tetrabutylammonium fluoride solution (1M TBAF in THF, 5 ml, 5.0 mmol). The solution is stirred for 2 hours after which water is added to the reaction and this is extracted in ethyl acetate. The organic layer is then washed with water, dried and concentrated. The residue obtained is purified by flash chromatography (silica gel; ethyl acetate/hexanes).
