Procedure
To a solution of the dithialane prepared in 3F (0.424 g, 0.86 mmoles) in dry methylene chloride (4 ml) was added at room temperature trimethyloxonium tetrafluoroborate (0.125 g, 0.86 mmoles) and the mixture was stirred for 1 hr. Then a 9:1 mixture of acetone and water (2 ml) containing calcium carbonate (0.172 g, 1.72 mmoles) was added and the mixture was stirred overnight at room temperature. The precipitate was filtered off and after dilution with saturated brine the mixture was extracted three times with ether. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to afford the expected aldehyde as an oil which was used after drying under high vacuum (0.366 g, 92%).
