describes a new route for the synthesis of N-(1′-homo-L-gulitol)nucleosides and amino sugar analogues of N-(1′-homo-L-gulitol)nucleosides by nucleophilic epoxide ring-opening followed by O-heterocyclization of 1,2:5,6-dianhydro-3,4-di-O-benzyl-D-mannitol and 1,2:5,6-dianhydro-3,4-diazido-D-iditol, respectively. Magnesium perchlorate [Mg(ClO4)2] was found to be the best catalyst for the reaction of silylated
本文描述了一种通过亲核环氧化物开环和 O 合成 N-(1'-homo-L-gulitol) 核苷和 N-(1'-homo-L-gulitol) 核苷的氨基糖类似物的新途径- 1,2:5,6-dianhydro-3,4-di-O-benzyl-D-mannitol 和 1,2:5,6-dianhydro-3,4-diazido-D-iditol 的杂环化。发现高氯酸镁 [Mg(ClO4)2] 是甲硅烷基化碱(衍生自尿嘧啶、胸腺嘧啶和腺嘌呤)与这些双(环氧化物)反应的最佳催化剂。(© Wiley-VCH Verlag GmbH & Co.
