실험 절차
To a stirred solution of 2-4 (422 mg, 1.92 mmol) in TBF was added 5.75 mL of 9-BBN (0.5 M/THF). After 18 hours, a slurry of NaBO3 (2.35 g) and NaHCO3 (2.42 g) in H2O (10 mL) was added and the mixture stirred vigorously for 1 hour. The mixture was extracted with CHCl3, washed with brine, and dried over MgSO4. Following evaporative removal of the solvent, the residue was chromatographed (silica gel, 3% EtOH/EtOAc) to give 2-5 as a clear oil.
