Reaction Conditions

Reaction Steps

To 7-methoxy-2,3,4,4a,9,9a-hexahydro-1H-fluorene (1.95 g, 9.65 mmol) in CH2Cl2 (20 mL) was added BBr3 (1M in CH2Cl2, 24 mmol) dropwise at 0° C. This mixture was stirred at 0° C. for one hour. The reaction mixture was then quenched with MeOH (5 mL). Aqueous sodium hydrogen carbonate (10 mL) was added. The reaction mixture was stirred at room temperature overnight. The reaction mixture was extracted with CH2Cl2. The organic phase was washed with brine, dried (Na2SO4) and concentrated. Silica gel chromatography (EtOAc/heptane) provided 1.48 g of 5,6,7,8,8a,9-hexahydro-4bH-fluoren-2-ol.
