摘要: 以竹红菌甲素作敏化剂匹配高压钠灯产生单重态氧,在甲醇溶液中,氧化6-取代-1,4-环辛二烯(1),(2),并经亚硫酸钠还原,得到顺-5,8-二取代-1,3-环辛二烯和反-5,6-二取代-1,3-环辛二烯发。化合物(3)是在三氯乙烷溶液中,未经还原得到过氧化氢基取代-1,3-环辛二烯。基态分子的稳定构象决定了反应产物的立体选择性。这类反应为用光氧化方法合成顺-5,8-二取代和反-5,6-二取代-1,3-环辛二烯含氧衍生物提供了方便的途径。

Abstract: Hypocrellin A sensitized photooxygenation of 6-hydroxy-l,4-cyclooctadiene, 6-methoxy-1,4-cyclooctadiene, in methanol and 6-trimethylsiloxy-l,4-cyclooctadiene in 1,1,1-trichloroetha-ne stereoselectively got cis-5,8-disubstituted-l,3-cyclooctadiene and trans-5,6-disubstituted-l,3-cyclooctadiene respectively due to the stable conformation of starting material molecules in the ground state. Therefore a convenient simultaneous synthetic entry into cis-5,8-disubstituted-l,3-cyclooctadiene and trans-5,6-disubstituted-l,3-cydooctadiene has been introduced.
