실험 절차

To a solution of 9-formyl-7,12-dioxaspiro[5,6]dodecane of formula IV (5 g) in methanol (15 ml) was added in small portions NaBH4 (0.5 g) while stirring the solution and maintaining the temperature at 10° C. After complete addition, the reaction mixture was stirred for 3 hr at 20° C. The product residue obtained after evaporation of methanol was treated with water (20 ml), extracted into ether and dried over K2CO3. Evaporation of ether gave 9-hydroxymethyl-7, 12-dioxaspiro[5,6]dodecane of formula V (5 g) of the drawings as colorless viscous liquid.
