The photo-sensitized oxygenation of monocyclic 1H-1, 3-diazepines (6) gave several fragment products (7-12). 3-Pyrrolin-2-one derivatives (7 and 8) and ethyl aminoformates (9 and 10) are assumed to originate from the initially formed 4, 7-endoperoxides (13), and vinylaminoformates (11 and 12) from the 4, 5-dioxetanes (14).
单环1H-1,3-二氮杂卓(6)的光敏氧化反应产生了多个片段产物(7-12)。3-吡咯啉-2-酮衍生物(7和8)和乙基氨基甲酸酯(9和10)被认为来自最初形成的4,7-内过氧化物(13),乙烯基氨基甲酸酯(11和12)来自4,5-二氧杂环丁烷(14)。
