Reaktionsschritte
To a diethyl ether (150 ml) solution of 2,2-dimethyl-1,3-dioxan-5-one (15 g, 0.115 mol), lithium aluminum hydride (4.38 g, 0.115 mol) was added at 0 to 8° C. for one hour in a nitrogen atmosphere. To the reaction mixture, water (4.2 ml), a 5N aqueous sodium hydroxide solution (4.2 ml), and water (12.8 ml) were sequentially added dropwise at 0 to 10° C. The mixture was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to obtain the title compound (14.2 g, 93.4%) as a colorless oil.
