실험 절차

A mixture of 270 mg (1.66 mmol) of (-)-6-chloromethyltetrahydropyran-2,4-dione obtained in Example 1, 10 mg platinum dioxide and 100 ml of ethyl acetate was stirred for 7 hours under hydrogen atmosphere. After completion of the reaction, the catalyst was removed by filtration, and the solvent was distilled off to obtain 199.6 mg (yield 73%) of (+)-6-chloromethyl-4-hydroxytetrahydropyran-2-one [a compound of the formula (3)] having
