摘要

hypsampsone A是一种复杂的巯基萜类化合物，其生物遗传学起源的简化建议得到了生物启发级联反应的支持，该反应可快速组装其多环核心。提出的生物合成和生物启发级联的关键步骤是自发的分子内羰基烯反应，α-羟基-β-二酮重排和分子内终止醛醇反应。该模型级联反应的可行性强烈表明，hypsampsone A是天然产物多环聚丙烯酰化酰基间苯三酚（PPAP）家族的高度重排成员。

A synthetic investigation into the biosynthesis of hypsampsone A†

A simplified proposal for the biogenetic origin of hypsampsone A, a complex meroterpenoid, is supported by a bioinspired cascade reaction that rapidly assembles its polycyclic core. The key steps in both the proposed biosynthesis and the bioinspired cascade are a spontaneous intramolecular carbonyl–ene reaction, an α-hydroxy-β-diketone rearrangement and a terminating intramolecular aldol reaction. The feasibility of this model cascade reaction strongly suggests that hypsampsone A is a highly rearranged member of the polycyclic polyprenylated acylphloroglucinol (PPAP) family of natural products.
