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
研究了三种类型的α-雪松烯(CED)的光敏氧合,包括:乙腈中玫瑰孟加拉(RB)致敏的αα-雪松烯的光氧合产生了一种主要的立体特异产物(cedr-8-exoen-9αα-ol ),其中双键迁移到相邻位置,该结果证明了单线态氧过程;9,10-二氰基蒽(DCA)敏化的光氧化作用导致cedr-8-en-10?β-ol的形成; 苄基(BZ)敏化的光环氧化反应提供了立体定向的8′α,9′α-雪松烯环氧化物,该反应包括自由基反应机理。
