caulamidines possess an additional carbon atom of unknown biosynthetic origins, which renders their entire skeleton nonsymmetric and nondimeric. Herein, we report the first totalsynthesis of caulamidine A and confirm its absolute configuration. Key chemical findings include the exploitation of glycol bistriflate to facilitate a rapid, diastereoselective ketone-amidine annulation reaction and a highly diastereoselective
海洋苔藓虫继续提供结构上令人着迷的卤化生物碱,这对化学合成提出了独特的挑战。最近从Caulibugula intermis中分离出的抗疟生物碱 caulamidines A 和 B含有复杂的双脒核心和含氯新戊基立构中心。与拓扑相似的 C 20相比双(环色胺)生物碱,椰脒具有生物合成来源未知的额外碳原子,这使得它们的整个骨架不对称和非二聚体。在此,我们首次报道了 caulamidine A 的全合成并确认了其绝对构型。主要化学发现包括利用乙二醇二氟甲磺酸酯促进快速、非对映选择性酮-脒环化反应和高度非对映选择性氢原子转移以正确建立关键的含氯立构中心。

The intramolecular dimerization of unsymmetrical bis-1,2-(3-indolyl)ethanes could be controlled using either thermodynamic reaction conditions (neat trifluoroacetic acid) or kinetic conditions (2 equiv acid/chloroform). This control of regiochemistry has been applied to an efficient synthesis of (−)-tjipanazole F1.
