according to a biosynthetic hypothesis postulated by Hesse and Schmid. These oxidative cyclizations led selectively to the formation of the N1–C16 bond of pleiocarpamine or to the C7–C16 bond of strictamine. We were then able to obtain the scaffold of talbotine.
对于 mavacurane 和 akuammilane 单萜吲哚生物碱,我们根据 Hesse 和 Schmid 假设的生物合成假设,在吲哚核(N1 或 C7)和与胡豆苷相关的常见三环模型的 C16-丙二酸酯之间开发了不同的氧化偶联。这些氧化环化选择性地导致形成多果胺的 N1-C16 键或严格胺的 C7-C16 键。然后我们能够获得塔博汀的支架。
