The total synthesis of anti-inflammatory active flavone C-glycoside isolated from oolong tea extract is achieved. Introducing a C-glucosyl moiety to an aryl system and constructing a fused tetracyclic ring characteristic to this natural product were conducted based on the O-to-C rearrangement of sugar moiety and the successive intramolecular Mitsunobu reaction, respectively. This concise and efficient
从乌龙茶提取物中分离得到的抗炎活性黄酮C-糖苷的总合成得以实现。一个引入Ç -glucosyl部分与芳基系统和构建稠四环特性此天然产物进行基于所述被ø -到- Ç分别糖部分和连续的分子内Mitsunobu反应,重排。这种简洁有效的合成途径适用于目标黄酮的大规模合成,也可用于构建相关化合物的大型文库。
