Versuchsvorschrift

A solution of alcohol 12 (4.32 g, 21.6 mmol) in 40 mL of CH2Cl2 was treated with 4A molecular sieves, NMO (3.81 g, 32.5 mmol), and TPAP (381 mg, 1.08 mmol). The reaction was stirred for 10 min. and then was evaporated to dryness. Purification by flash chromatography on silica gel (2% ethyl acetate/hexane) gave 3.52 g (18.3 mmol, 84%) of the aldehyde (13).
