Versuchsvorschrift
The acetal 11 (287 mg, 850 mop was dissolved in MeOH (1 mL) and coned HCl (0.5 mL) was added to the solution, which was stirred for 1 h at 25° C. The reaction mixture was then evaporated to dryness; the material left was dissolved in CH2Cl2 (10 mL) and the solution was washed with NaHCO3 (2 mL of a saturated aqueous solution). The organic layer was collected and was evaporated under low pressure to give the aldehyde as a light green foam, the total amount of which was used without further purification in the preparation of 12.
