실험 절차

To a solution of (1R,3S,5R)-3-(((tert-butyldiphenylsilyl)oxy)methyl)-6,6-dimethyl-bicyclo[3.1.1]heptan-2-one O-methyl oxime, 77d, (0.20 g, 0.46 mmol) in THF (3 mL) was added borane-THF (1.38 mL of 1 M solution, 1.38 mmol). The reaction was heated to 75° C. for 18 hours. The mixture was diluted into 1N NaOH (50 mL) and extracted twice with EtOAc. The combined organic phases were dried (MgSO4), filtered and concentrated in vacuo to afford 178 mg of a colorless oil that was used without further purification: LCMS RT=2.53 (M+H) 408.54.
