描述了真菌代谢物 preuisolactone A 的简短仿生合成。其关键步骤是 purpurogal-lin 型 (5+2)-环加成,然后是碎裂、乙烯醇醛加成、氧化内酯化和最终的苯甲酸重排。我们的工作解释了为什么 preuisolactone A 被分离为外消旋物,并表明天然产物不是倍半萜烯而是酚类聚酮化合物。

A short, biomimeticsynthesis of the fungal metabolite preuisolactone A is described. Its key steps are a purpurogal-lin-type (5+2)-cycloaddition, followed by fragmentation, vinylogous aldol addition, oxidative lactonization and a final benzilic acid rearrangement. Our work explains why preuisolactone A has been isolated as a racemate and suggests that the natural product is not a sesquiterpene but
