Participants

Reaction Steps

Step F To the solution of tert-butyl-dimethyl-[2-((S)-2,2,5,5-tetramethyl-[1,3]dioxolan-4-yl)-ethoxy]-silane (4.56 g, 15.8 mmol) in tetrahydrofuran (20 mL) at 0° C. was added a solution of tetrabutylammonium fluoride (1 M, 20 mL, 20 mmol). The reaction mixture was stirred at room temperature for 1 h. Water was added, and the mixture was extracted with ethyl acetate. The organic layer was separated, washed with saturated aqueous NaHCO3 solution, brine, dried over MgSO4, and concentrated to give 2-((S)-2,2,5,5-tetramethyl-[1,3]dioxolan-4-yl)-ethanol as a yellow oil (2.7 g, 100%).
