Hydrochloric Acid → 3,3-Dimethylpentane-1,5-diol

Participants

Reaction Steps

Step A To the solution of 3,3-dimethylglutaric acid (Aldrich) (5.1 g, 32 mmol) in anhydrous tetrahydrofuran (100 mL) at 0° C. was added a solution of BH3.THF (1 M, 100 mL, 100 mmol). The reaction mixture was stirred at room temperature for 18 h. Aqueous HCl solution 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. The residue was purified by chromatography (EtOAc) to give 3,3-dimethyl-pentane-1,5-diol as a colorless oil (1.5 g, 34%).
