A short, formal synthesis of (±)-tylophorine was achieved using a radical–ionic sequence for the preparation of epoxides as the key step. This sequence, carried out between a phenantrenic allylic alcohol and iodoacetonitrile, provided an advanced intermediate containing most of the required elements for the final construction of the indolizidine scaffold.
使用自由基 - 离子序列作为关键步骤制备环氧化物,实现了 (±)-tylophorine 的简短正式合成。该序列在菲烯丙醇和碘乙腈之间进行,提供了一种高级中间体,其中包含大多数用于最终构建吲哚里西啶支架所需的元素。
