Tetrahydrofuran → HCID 20099906, compound

Participants

Reaction Steps

To a stirred solution of 75 (0.12 g, 0.42 mmol) in anhydrous THF (10 mL) at −78° C., under a nitrogen atmosphere was added diisobutylaluminum hydride (0.5 mL, 0-5 mmol, using a 1M solution in hexane) dropwise. The reaction mixture was stirred at the same temperature for 1 hour and then quenched by dropwise addition of potassium sodium tartrate (10% solution in water). The resulting mixture was warmed to room temperature, diluted with diethyl ether (20 mL) and stirred vigorously for 1 h. The organic phase was separated and the aqueous phase was extracted with diethyl ether. The combined organic layer was washed with brine, dried (MgSO4) and evaporated under reduced pressure. The residue obtained was purified by flash column chromatography on silica gel (20% diethyl ether-hexane) to give 76 (0.091 g, 75% yield) as a viscous liquid.
