3]-oxathiazepane-2,2- dioxides allows straightforward access to aminoglycosides with selective alpha- or beta-linkages. This approach is operationally simple, complements existing methods, and is a versatile protocol for the synthesis of polyfunctionalized amino sugars. In addition, the mechanism of the rhodium-catalyzed intramolecular aziridination of glycals and its ring-opening reaction was extensively studied
糖衍生的氨基磺酸盐的立体控制的分子内叠氮化提供了一种高效地策略以发散地制备氨基糖苷。铑催化的氮原子转移至C == C键形成了半稳定的氮丙啶,对它们进行了各种亲核试剂(C,O,S和N)处理,可以选择性地生成含环状氨基磺酸酯的氨基糖衍生物。[1,2,3]-氧杂ze庚烷-2,2-二氧化物的磺酰氧基部分的第二次亲核置换可直接获得具有选择性α-或β-键的氨基糖苷。该方法操作简单,是对现有方法的补充,是多官能氨基糖合成的通用协议。此外,
