Bicyclo(3.3.1)nonanes as synthetic intermediates. XVII. A novel interconversion between bicyclo(4.3.1)decane and tricyclo(4.3.1.0)decane systems via the dual mode of aldol cyclization of bicyclo(4.3.1)decane-3,8-dione.

The characteristics intramolecular aldol cyclization of bicyclo[4.3.1]decanedione to two novel tricyclic systems, protoadamantanone and isotwistanone, is described. Both systems were reconverted to bicyclo[4.3.1]decanones by the Grob fragmentation.
本文描述了双环[4.3.1]癸二酮分子内醛缩环反应生成两个新颖的三环系统——原金刚烷酮和异金刚烷酮的特征。通过格罗布断裂,这两个系统都重新转化为双环[4.3.1]癸二酮。
