Absolute structure of catalponol, a naphthoquinone congener of Catalpa ovata has been established as 1. Examination of the reaction of 1 and its oxidation product, catalponone (2) with BF3 giving several derivatives including natural products such as 2, 2-dimethylnaph-thochroman (12), nordihydrolapachenole (14) and tetrahydrotectol (15), has offered interesting materials for considering the biosynthetic pathway of these substances.
1 及其氧化产物 catalponone (2) 与 BF3 反应生成多种衍生物,其中包括天然产物,如 2,2-二甲基萘-色满 (12)、正二氢紫苏烯 (14) 和四氢紫苏烯醇 (15),为研究这些物质的生物合成途径提供了有趣的材料。
