Abstract A practical synthesis of 7-methylenebicyclo[3.3.1]nonan-3-one 2 by the fragmentation of 1,3-adamantanediol 8, which was prepared effectively by the ruthenium-catalized oxyfunctionalization of 1-adamantanol 7, is described. Characteristic transannular cyclization of 2 leading to a novel tricyclic system, 1-hydroxy-4-protoadamantanone 9, via the corresponding exo-epoxide 10 is also presented
摘要 描述了 7-亚甲基双环[3.3.1]壬烷-3-one 2 的实际合成方法,该方法是通过 1-金刚烷醇 7 的钌催化氧官能化有效制备的 1,3-金刚烷二醇 8 裂解制备的。还介绍了 2 的特征性环化环化,通过相应的外环氧化物 10 产生了一个新的三环系统,1-羟基-4-原金刚烷酮 9。
