An effective and facile method for the synthesis of 2-substituted perhydrofuro[2,3-b]pyran derivatives is described. The cyclization of 2-C-aldehydo-2-deoxy-D-thioglucoside in the presence of N-iodosuccinimide (NIS) is highly stereoselective. 2-Substituted cyclization products were obtained in good to excellent yields.
描述了一种有效且简便的合成 2-取代全氢呋喃并[2,3-b]吡喃衍生物的方法。在 N-碘代丁二酰亚胺（NIS）存在下，2-C-醛基-2-去氧-D-硫代葡萄糖苷的环化反应具有高度的立体选择性。得到了 2-取代的环化产物，产率良好至优秀。
