efficient and highly stereoselective synthesis of L-ido-aminoiminosugar 3 has been described. Key in the synthesis is the application of a diastereoselective Strecker reaction and the extension of our carbamate annulation methodology to protected and functionalized alkenylamines. In addition, the identification of the primary iodide as a key intermediate during the carbamate annulation reaction provides
已经描述了 L-ido-氨基亚氨基糖 3 的高效和高度立体选择性合成。合成的关键是应用非对映选择性 Strecker 反应,并将我们的氨基甲酸酯环化方法扩展到受保护和功能化的链烯胺。此外,在氨基甲酸酯环化反应过程中,初级碘化物作为关键中间体的鉴定提供了对该反应机理的深入了解。
