Total synthesis of the natural acetyl-β-D-glucoside blepharin (1) and its C-2′ epimer 9 by treatment of 2-bromo-2H-1, 4-benzoxazin-3(4H)-one (5) with 2,3,4,6-tetra-O-acetyl-β-D-glucopyranose (6) is described. The relative and absolute configuration of 1 was determined by 1H-NMR and X-ray analysis.
通过 2-溴-2H-1, 4-苯并恶嗪-3(4H)-酮 (5) 与 2,3,4,6-四-O-乙酰基-δ²-D-吡喃葡萄糖 (6) 的处理,描述了天然乙酰基-δ-D-葡萄糖苷漂白素 (1) 及其 C-2′ 表聚物 9 的全合成。通过 1H-NMR 和 X 射线分析确定了 1 的相对和绝对构型。
