  Synthesis of C-D-E trisaccharide precursors of olivomycin A.

  摘要：

  Syntheses of functionalized C-D-E trisaccharide precursors (16, 5) of olivomycin A are reported. A stereoselective C-D beta-glycosidation was accomplished by employing 2-deoxy-2-(phenylthio)-alpha-glucotrichloro-acetimidate 8. The alpha-D-E glycosidic linkage was introduced by using 2-deoxy-2-iodo-alpha-glycosyl acetate donor 14 as the glycosyl transfer agent.

  [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.

  乙酸与硝酸铈（IV）铵盐和碘化钠在乙酸存在下的反应，可得到具有良好立体选择性的2-脱氧-2-碘-α-甘露吡喃糖基乙酸酯。在大多数检查的情况下，其选择性明显优于使用N-碘代琥珀酰亚胺和HOAc的反应。
