실험 절차
To a solution of (5S)-((3R,3aR,6R,6aR)-6-(tetrahydro-2H-pyran-2-yloxy)hexahydrofuro[3,2-b]furan-3-yl) 5,6-bis(nitrooxy)hexanoate (2.27 g, 5.04 mmol) in ethanol (40 mL) pyridinium p-toluensulfonate (127 mg, 0.504 mmol) was added The reaction mixture was stirred at 45° C. for 4 hrs. The reaction mixture was filtered, concentrated under reduced pressure. The crude residue was purified by flash chromatography (Biotage SP1, EtOAc/n-hexane from 10 to 60%), affording the title product as pale yellow oil.
