Mycosamine is a dideoxyaminosugar found in medicinally relevant macrolides, including amphotericin B and nystatin. Herein we report a reliable, high yielding, scalable synthesis of a mycosamine donor. A major goal of our approach was to minimize purifications via judicious selection of protecting groups; the inherent properties of the allose framework created some deprotection obstacles that were ultimately
Mycosamine 是一种双脱氧氨基糖,存在于药用相关的大环内酯类药物中,包括两性霉素 B 和制霉菌素。在此,我们报告了一种可靠、高产、可扩展的糖胺供体合成方法。我们方法的一个主要目标是通过明智地选择保护基团来最大限度地减少纯化;allose 框架的固有特性造成了一些最终得到解决的去保护障碍。
