Thirteen newanalogues of diterpenoid alkaloids were synthesized from the potassium ion channel blocker talatisamine (1) by means of the ring-distortion strategy. Most of these derivatives are unique by featuring differentiated CD rings compared to the corresponding naturally-occurring alkaloids. Remarkable transformations including a novel rearrangement (1→7 and 13→7), an intriguing fragmentation
通过环畸变策略,由钾离子通道阻滞剂塔拉他胺(1)合成了13种新的二萜类生物碱类似物。与相应的天然生物碱相比,这些衍生物大多数具有独特的CD环特征。显着转变,包括一种新颖的重排(1 → 7和13 → 7),一个有趣的片段化(16 → 8),以前所未有的C-的制备一起均聚- d -nor衍生物12,在该研究中所公开的。
