Procedure

3S,3aR,6S,6aR)-6-(tetrahydro-2H-pyran-2-yloxy)hexahydrofuro[3,2-b]furan-3-ol (0.64 g, 2.80 mmol) and (5R)-5,6-bis-nitrooxy-hexanoic acid (1.18 g, 4.95 mmol) (obtained as described in EXAMPLE 5) were dissolved in DCM (30 ml), EDAC (0.81 g, 4.20 mmol) and 4-dimethylaminopyridine (0.068 g, 0.56 mmol) were added. After stirring at room temperature for 12 hrs, the reaction mixture was washed with water. The organic layer was dried over sodium sulfate, and evaporated under reduced pressure. The residue was purified by flash chromatography (Biotage SP1, EtOAc/n-hexane from 10 to 80%), affording the title product as an oil.
