Starting from an l-serine-derived multifunctional aminobutenolide as a common chiral building block, stereoselective synthetic routes to representative examples of di-, tri-, and tetrahydroxylated iminosugars have been developed. Key steps in the synthetic routes involved an intramolecular aminolysis protocol to form the azaheterocyclic core, and functionalization of a resident alkene moiety towards
从L-丝氨酸衍生的多功能氨基丁烯酸内酯作为常见的手性结构单元开始,已经开发出二羟基、三羟基和四羟基化亚氨基糖的代表性实例的立体选择性合成路线。合成路线的关键步骤涉及分子内氨解方案以形成氮杂杂环核心,以及对常驻烯烃部分进行官能化以在哌啶环的各个位置安装所需的取代基。所描述的策略和方法有望为具有结构和药物化学意义的各种亚氨基糖支架提供灵活的合成路线。
