Procedure

To a solution of (3R,3aR,6R,6aR)-6-(tetrahydro-2H-pyran-2-yloxy)hexahydrofuro[3,2-b]furan-3-ol (2.96 g, 12.9 mmol) in DCM (40.8 mL) a solution of the crude (S)-5,6-di(nitrooxy)hexanoic acid (3.06 g, 12.85 mmol) (Step D) in DCM (9.15 mL) was added followed by EDAC (3.69 g, 19.28 mmol) and 4-dimethylaminopyridine (175 mg, 1.28 mmol). The reaction mixture was stirred at rt for 16.5 hrs. The solvent was removed 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.
