A plausible biosynthetic pathway for the isomeric marine alkaloids papuamine and haliclonadiamine via the double tandem ene cyclisation of a tetraenediimine is proposed. Initial model studies directed toward the biomimetic synthesis of these alkaloids are described which illustrate that the Lewis acid-promoted ene cyclisation of methyl-2-(methoxycarbonyl)dodeca-2,8-dienoate is critically dependent
提出了经由四烯二胺的双串联烯环化的异构海洋生物碱巴布胺和卤代丙二胺的可能的生物合成途径。描述了针对这些生物碱的仿生合成的初始模型研究,这些研究表明2-(甲氧基羰基)dodeca-2,8-二烯酸甲酯的路易斯酸促进的烯环化主要取决于Δ-8几何形状。
