A novel approach to the Aspidosperma family of alkaloids was developed and applied to a concise total synthesis of (±)-pseudotabersonine that was accomplished in 11 steps. Key transformations include a stepwise variant of a Mannich-like multicomponent assembly process, a double ring-closing metathesis sequence, and a one-pot deprotection/cyclization reaction.
开发了一种新的方法用于曲霉属生物碱类,并将其应用于简明的(±)-假烟碱的全合成中,该合成过程可分11个步骤完成。关键的转化包括曼尼希样多组分组装过程的逐步变体,双闭环复分解序列和一锅脱保护/环化反应。
