Chemical evidence has been obtained in two separate experiments for the participation of a perepoxide intermediate in the reaction of singlet oxygen with mono-olefins. The intramolecular trapping of such an intermediate in the reaction of 6,7-didehydrocarnosic acid derivatives with molecular oxygen in unequivocal singlet oxygen-generating conditions to give rosmanol and isorosmanol derivatives represents
在两个单独的实验中已获得化学证据,证明过氧化物中间体参与单线态氧与单烯烃的反应。在6,7-二氢戊糖酸衍生物与分子氧在明确的单线态氧生成条件下反应生成分子香豆酚和异香豆酚衍生物的过程中,这种中间体的分子内捕集为上述机理提供了确凿的证据。此外,这些化学证据支持了我们先前关于高氧化己二三烯二萜生物遗传途径的假说,其中酶促脱氢和单重态氧似乎起着重要作用。
