Herein we report the asymmetric syntheses of a number of oxygenated terpenoids that are of importance in the chemical ecology of bark beetles. These are pinocamphones, isopinocamphones, pinocarvones, and 4-thujanols (= sabinene hydrates). The camphones were synthesized from isopinocampheol, the pinocarvones from β-pinene, and the thujanols from sabinene. The NMR spectroscopic data, specific rotations
在此,我们报告了许多含氧萜类化合物的不对称合成,这些萜类化合物在树皮甲虫的化学生态学中具有重要意义。它们是松蒎酮、异松蒎酮、松香芹酮和 4-侧柏烯醇(= 桧烯水合物)。樟脑由异松蒎酚合成,松香芹酮由β-蒎烯合成,侧柏酚由桧烯合成。还报道了其立体异构体在手性 GC 相(β-环糊精)上的 NMR 光谱数据、比旋光度和洗脱顺序。这使得能够轻松合成纯化合物,用于生物活性研究和混合天然样品中立体异构体的鉴定。
