실험 절차
To a mixture of the ether (151 mg) (Step 2) and thioglycolic acid (31 μL) in CH2Cl2 at 0° C. was added BF3 /OEt2 (117 μL) dropwise. The mixture was stirred at 0° C. for 1 h and poured onto 25% aqueous NH4OAc, extracted with CH2Cl2 and the organic phase was dried and evaporated. Chromatography on silica gel using ethyl acetate/hexane containing 0.1% AcOH afforded the title compound.
