The first total synthesis of (±)-subincanadine F, a bioactive indole alkaloid structurally featuring a 1-azabicyclo[4.3.1]decane unit, has been realized from 1-(para-methoxybenzyl)tryptamine in six steps. The bridge-containing tetracyclic framework of subincanadine F was efficiently assembled by a SmI2-mediated ring opening followed by an acid-mediated Mannich reaction. In addition, the tetracyclic
从1-(对甲氧基苄基)色胺中分六步完成了第一个全合成的(±)-亚辛那啶F,这是一种生物活性的吲哚生物碱,结构上具有1-氮杂双环[4.3.1]癸烷单元。亚辛达那碱F的含桥四环骨架通过SmI 2介导的开环,随后酸介导的曼尼希反应而有效地组装。此外,四环酮酸酯6(也可能用于合成结构相关的吲哚生物碱的关键中间体)一步从α,β-二酮酸酯5中获得。
