We achieved the first total synthesis of (±)-incargutines A and B, which were isolated from the roots of Incarvillea arguta, utilizing In(OTf)3-catalyzed enolization of cyclohexenone derivatives subsequent to an intramolecular Alder–Rickert reaction. At first, we synthesized the proposed structures of incargutines A and B. The spectral data of the synthetic proposed compounds did not correspond to
我们利用 In(OTf)3 催化的环己烯酮衍生物在分子内 Alder-Rickert 反应后的烯醇化,实现了 (±)-incargutines A 和 B 的首次全合成,它们是从 Incarvillea arguta 的根中分离出来的。首先,我们合成了incargutines A 和B 的拟议结构。合成的拟议化合物的光谱数据与天然产物的光谱数据不一致。然后,我们合成了所提出结构的甲基区域异构体。这些合成化合物的光谱数据与天然incargutines A 和B 的光谱数据相同。因此,incargutines A 和B 的结构被明确确定为甲基区域异构体。
