  Structures of Fukinone Epoxides. Configuration, Conformation, and CD Spectra

  摘要：

  The configuration and conformation of two diastereoisomeric fukinone epoxides were unambiguously established by NMR (NOESY), CD, and X-ray crystallographic analyses of their derivatives. The data show the absolute configurations of exo alpha,beta-epoxy ketones can be predicted by an octant rule, not by a Reverse Octant Rule.

• The Transformations of Terpene Eetones by Oxygen. II. The Base-catalyzed Autoxidation of Pulegone and Fukinone and Their Dihydro Compounds

  Upon autoxidation in alkaline media, pulegone and fukinone (2) gave pairs of hydroxy ketones respectively as the major products; also, hydroxyeremophilone was isolated as its acetate from 2. On the other hand, their dihydro compounds afforded hydroxy ketones, diosphenols, and acids.

  在碱性介质中自氧化时，普尔根和富基酮（2）分别生成一对羟基酮作为主要产物；此外，还从2中分离得到了羟基埃瑞莫菲酮的醋酸酯。另一方面，它们的二氢化合物则产生了羟基酮、二氧苯酚和酸。
