Versuchsvorschrift
A solution of 3-(tert-butyl-diphenylsilyloxy)-1-propanol (1 mmole) in methylene chloride (7 mL) was treated with powder molecular sieves (4 A, 0.5 equiv. wt/wt) and pyridinium chlorochromate (1.5 mmole) at 0° C. The resulting mixture was stirred at room temperature for 2 h, and diluted with diethyl ether (7 mL) and stirred at room temperature for another 30 min. Filtration, evaporation and chromatography gave 3-(tert-butyldiphenylsilyloxy)-1-propanal as a clear oil.
