Participants

Reaction Steps

3 g of 1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3 (1H)-one (Dess-Martin Periodinane) was added to a solution of 1.8 g of (1R)-1-((4S,5S)-5-(hydroxymethyl)-2,2-dimethyl-1,3-dioxolane-4-yl)ethyl methanesulfonate (which contained fluorotris(propan-2-yl)silane) and 1.16 mL of pyridine in 20 mL of dichloromethane at a temperature of 5° C. to 10° C., and the obtained mixture was then stirred at room temperature for 2 hours. Thereafter, ethyl acetate, a saturated sodium hydrogen carbonate aqueous solution and a sodium thiosulfate aqueous solution were added to the reaction mixture. The organic layer was fractionated, and it was successively washed with water and a saturated sodium chloride aqueous solution and was then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure, so as to obtain 1.7 g of (1R)-1-((4S,5R)-5-formyl-2,2-dimethyl-1,3-dioxolane-4-yl)ethyl methanesulfonate in the form of a yellow oily product.
