Procedure

The above alcohol (60 mg, 0.21 mmol) was dissolved in dichloromethane (5.0 mL) and Dess-Martin reagent (2×135 mg, 0.63 mmol) was added in two portions and stirred for 60 min. A saturated solution of sodium bicarbonate (3.0 mL) was added, followed by solid sodium thiosulfate. The mixture was stirred vigorously and extracted with dichloromethane. The organic layer was washed with water (2×5 mL), brine (2×5 mL) and dried over MgSO4. The solvent was evaporated and the residue was purified over a short silica gel chromatography column to give 48 mg of the desired aldehyde, (+)-2-(1,2,3,4,5,6,7,8-octahydro-5,5,8,8-tetramethylanthracen-1-yl)ethan-1-al (81% yield).
