To a stirred solution of [(3aS,5S,6aS)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxol-5-yl]methanol (compound 25e, 2 g, 11.5 mmol) in THF (20 mL) was added Dess-Martine periodinane (7.2 g, 17.2 mmol). After being stirred room temperature for 2 hours, the resulting solution was filtered and the filtrate was concentrated in vacuo. The residue was purified by column chromatography on silica gel (eluting with 1:3 EtOAc in petroleum ether) to afford 1.2 g of (3aS,5S,6aS)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxole-5-carbaldehyde (compound 25f). MS obsd. (ESI+) [(M+NH4)+]: 190.
