실험 절차
The tetrahydropyranyl derivative prepared in 2C (2.26 g, 4.8 mmoles) was dissolved in methanol. Tetrabutyl-1,3-diisothiocyanatodistannoxane (30 mg) was added and the mixture was refluxed for 24 hrs. Methanol was evaporated under reduced pressure. The residue was dissolved in ether and washed with water. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. Flash chromatography on silicagel and elution with a 2:8 mixture of hexane and ethyl acetate afforded the alcohol as an oil (1.65 g, 92%).
