six-membered hemiacetal, a seven-membered oxazepane, and a dimethylpyrrolecarboxy group. By a novel and simple convergent strategy involving Pd/Ag-promoted Suzuki–Miyaura coupling and Dieckmann condensation reactions, the total synthesis of batrachotoxin was realized in 22 steps.
蝙蝠毒素是一种极强的心脏和神经毒性甾体
生物碱。其 6/6/6/5 元碳环骨架由两个双键、一个六元
半缩醛、一个七元氧杂氮杂
环己烷和一个二甲基
吡咯羧基官能化。通过一种新颖而简单的收敛策略,包括 Pd/Ag 促进的 Suzuki-Miyaura 偶联和 Dieckmann 缩合反应,只需 22 个步骤即可实现箭毒毒素的全合成。
