The complete details of the synthesis of sporol (1) and its formerly assigned structure, neosporol (2), are provided. A highly stereoselective Claisen rearrangement sets the C 5 -C 6 stereochemistry of the trichothecene skeleton. Subsequent functional group manipulation and ring closures led to the pentacyclic structures. The 1 H NMR studies that led to the structure reassignment are also discussed
提供了 sporol (1) 及其先前指定的结构 Neosporol (2) 合成的完整细节。高度立体选择性的克莱森重排设定了单端孢霉烯骨架的 C 5 -C 6 立体化学。随后的官能团操作和闭环导致了五环结构。还讨论了导致结构重新分配的 1 H NMR 研究
