(1R,2S)-1,2-Cyclooctanediol → Octanedial

262 ml of aqueous NaIO4 was added drop wise to a vigorously stirred suspension of 105 g chromatographic grade silica gel in 500 ml dichloromethane whereby a white suspension was formed. To the suspension a solution of 6.1 g cis-1,2-cyclo-octanediol in 100 ml dichloromethane was added. The reaction mixture was stirred over night at room temperature, after which the mixture was filtered whereby the residue was washed 3 times with 100 ml dichloromethane. Finally the filtrate was dried over NaSO4, after which the solvent was removed under reduced pressure.
