实验步骤: After 260 mg of lead tetraacetate was added at 4° C. to a mixture of 200 mg of the diol [27] described above, 60 mg of potassium carbonate and 4.5 ml of anhydrous benzene, the mixture was stirred for 3 minutes. After completion of the reaction, 100 ml of hexane was added to the reaction solution. The reaction solution was filtered through Celite 545 and the filtrate was washed with saturated sodium bicarbonate aqueous solution. The aqueous phase was extracted with hexane twice. The extracts were combined and washed with saturated sodium chloride aqueous solution. After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl ether:hexane=1:2 (volume)) to give 160 mg (yield, 80%) of (S) 2-benzyloxyheptanal [2]. was added to the reaction solution The reaction solution was filtered through Celite 545 the filtrate was washed with saturated sodium bicarbonate aqueous solution The aqueous phase was extracted with hexane twice washed with saturated sodium chloride aqueous solution After drying over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure The residue was purified by silica gel column chromatography (ethyl ether:hexane=1:2 (volume)) to give
