Abstract
本发明公开了一种无保护的芳基C‑糖苷的合成方法及应用，涉及化学和医药技术领域。合成方法包括：在惰性气体保护下，将无保护糖基供体、受体、光催化剂、过渡金属催化剂、配体、碱、自由基前体和溶剂进行反应，得到芳基C‑糖苷。本发明所要解决的问题是现有无保护芳基C‑糖苷合成需要多步保护基操作、反应条件苛刻且成本高，本发明直接利用全羟基糖类供体进行糖苷化反应，能简化合成路线，为后期官能团化及生物活性筛选提供更直接的途径，且本发明方法还能用于合成SGLT2抑制剂类药物，相较于传统合成路线需要超低温条件（‑78 ℃）和多步保护基引入和脱除策略，本发明能在室温下进行，避免昂贵试剂的使用和多步繁琐的纯化步骤。
