Procedure

To a solution of the product from Step 1 (30 mg, 0.053 mmol) in acetone (1 ml) and water (1 mL) was added potassium osmate dehydrate (19.61 mg, 0.053 mmol). The reaction was stirred at room temperature for 10 minutes after which sodium periodate (114 mg, 0.532 mmol) was added. After stirring for 2 hours, an additional 15 mg of potassium osmate and 115 mg of sodium periodate were added. After stirring 16 hours, the reaction was filtered and the solid was washed with acetone. The filtrate was concentrated, diluted with EtOAc and washed with Na2S2O3 and NaHCO3 aq. soln. Purification by PTLC (30% EtOAc-hexane) provided the desired aldehyde.
