Versuchsvorschrift

A suspension of 0.76 g of lithium aluminum hydride in 10 mL of tetrahydrofuran was cooled to 0° C. under a nitrogen atmosphere. To the suspension was added dropwise a solution of 2.18 g of methyl 1,4-dioxaspiro[4.5]decane-8-acetate in 10 mL of tetrahydrofuran, followed by stirring at room temperature for 3 hours. After the reaction mixture was cooled to 0° C., 1 mL of water was added thereto. The mixture was filtered through celite and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 1.73 g of 1,4-dioxaspiro[4.5]decane-8-ethanol represented by the following formula:
