Abstract

Three types of photosensitized oxygenations of α-cedrene (CED) were investigated, including: rose bengal (RB)-sensitized photooxygenation of α-cedrene in acetonitrile produced one major stereospecific product (cedr-8-exoen-9α-ol), in which the double bond migrated to an adjacent position, this result demonstrated the singlet oxygen process; 9, 10- dicyanoanthrathene (DCA) sensitized photooxygenation led to the formation of cedr-8-en- ...
