[formula: see text] The reactions of glycals with ceric(IV) ammonium nitrate and sodium iodide in the presence of acetic acid provides 2-deoxy-2-iodo-alpha-mannopyranosyl acetates with good stereoselectivity. In the majority of the cases examined, the selectivity was considerably better than that from reactions using N-iodosuccinimide and HOAc.
[化学式：见正文] 在乙酸存在下，糖醇与硝酸铈（IV）铵和碘化钠的反应以良好的立体选择性提供2-脱氧-2-碘-α-甘露吡喃糖基乙酸酯。在所研究的大多数情况下，该选择性比使用N-碘代琥珀酰亚胺和乙酸的反应的选择性要好得多。
