実験手順
To 200 ml of acetone were added 10.0 g of L-sorbose and 127 mg of iodine and the mixture was refluxed with stirring in a water bath at 60° C. for 6 hours. During this reaction, the refluxing solvent was dried with 20 g of Molecular Sieves 3A interposed between the reaction vessel and the cooling jacket. The reaction mixture was then subjected to an after-treatment similar to that described in Example 11 to give 11.15 g (77.2%) of 2,3:4,6-di-O-isopropylidene-L-sorbofuranose (purity ≥98.5%).
