Hydrogen Peroxide → 3-(1-{[Tert-butyl(dimethyl)silyl]oxy}cyclohexyl)propan-1-ol

Participants

Reaction Steps

A solution of borane in tetrahydrofuran (1 M, 15.7 mL, 15.7 mmol) was added to a solution of [(1-allylcyclohexyl)oxy](tert-butyl)dimethylsilane (8.00 g, 31.4 mmol) in tetrahydrofuran. After 2 h, water (5 mL) was added dropwise, followed by 3 M NaOH (6 mL), followed by dropwise addition of 30% aqueous hydrogen peroxide (6 mL). The mixture was stirred at rt for 1 h, then was diluted with diethyl ether (100 mL) and water (70 mL). The layers were separated and the aqueous layer was extracted with diethyl ether (2×35 mL). The combined organic layers were washed with brine (90 mL), dried over MgSO4, filtered, and concentrated to yield a colorless oil that was purified using HPFC (silica gel, gradient elution with 2-30% ethyl acetate/hexanes) to afford pure 3-(1-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)propan-1-ol (6.80 g, 79%).
