d-Glucopyranose-derived and l-idopyranose-derived piperidine nitrones were synthesized in good overall yields through six-step reaction sequence starting from readily available 2,3,4,6-tetra-O-benzyl-d-glucopyranose. The method is efficient and could be general for the synthesis of aldohexose-derived piperidine nitrones which are precursors of piperidine iminosugars.
从容易获得的 2,3,4,6-四-O-苄基-d-吡喃葡萄糖开始,通过六步反应序列以良好的总产率合成了 d-吡喃葡萄糖衍生的和 l-吡喃葡萄糖衍生的哌啶硝酮。该方法是有效的,可用于合成己醛糖衍生的哌啶硝酮,后者是哌啶亚氨基糖的前体。
