Grandisol (1) is one of the components of the pheromone complex emitted by the male boll weevil. We report the transformation of readily available eucarvone (3), via the photoisomer 4, into grandisol in 20% overall yield. A key step in the synthesis is the Beckmann cleavage of oxime 15, derived in three steps from 4, to nitrite 16. Hydrolysis of 16 followed by hydride reduction gives grandisol (1)
Grandisol (1) 是雄性棉铃象鼻虫释放的信息素复合物的成分之一。我们报告了容易获得的丁香酮 (3),通过光异构体 4,以 20% 的总产率转化为 Grandisol。合成中的一个关键步骤是将肟 15 进行贝克曼裂解,分三步从 4 衍生到亚硝酸盐 16。水解 16,然后进行氢化物还原,得到格兰迪醇 (1)。
