biological properties. While (–)-isoguaiacin has not been previously synthesized, syntheses of (–)-isogalbulin are generally long and produce a mixture of stereoisomers. We herein present the efficient total synthesis of (±)-isoguaiacin and (±)-isogalbulin in seven and eight steps with an overall yield of 46% and 36%, respectively. The reported approach harnesses a hydrogenolysis reaction in acidic conditions
据报道,1-芳基萘木脂素如 (-)-异愈创木酚和 (-)-异白蛋白具有显着的生物学特性。虽然之前没有合成 (-)-异愈创木酚苷,但 (-)-异白蛋白素的合成通常很长,并且会产生立体异构体的混合物。我们在此介绍了 (±)-异愈创木酚和 (±)-异白蛋白的有效全合成,分七步和八步,总产率分别为 46% 和 36%。报道的方法利用酸性条件下的氢解反应,将呋喃转化为芳基萘结构。
