core bearing a halogen atom enabled the introduction of the α C‐aryl glycoside by Stille cross‐coupling and subsequent hydrogenation of the aryl glycal. Chemo‐ and stereoselective O‐glycosylations of α oliose and β 3‐epi vancosamine residues afforded a fully glycosylated aromatic core. Attempts to install the dimethylamino group of the C‐disaccharide suggest that introduction of an azide group by displacement
已经开发了一种针对强效细胞抑制剂 pluraflavin A 的合成策略。带有卤素原子的对映体富集的蒽吡喃核心的形成使得 α C-芳基糖苷的引入能够通过 Stille 交叉偶联和随后的芳基糖基化。α oliose 和 β 3-epi 万考胺残基的化学和立体选择性 O-糖基化提供了完全糖基化的芳香族核心。安装 C-二糖的二甲基氨基的尝试表明,通过置换和随后的还原引入叠氮化物基团可能为多黄素 A 的完全合成铺平道路。
