  • Studies on diazepines. XVII. Synthesis of monocyclic 1,3-diazepines. (2). Substituent effects on the thermal ring-conversion of 1,2-diazepines into 1,3-diazepines.

    The thermolysis of 1, 2-diazepines (7a-f and 11) having an electron-donating substituent in the 4- or 6-position resulted in the formation of the 1, 3-diazepines (9 and 12) and 2-aminopyridines (10), whereas 1, 2-diazepines (7g-k) having an electron-withdrawing substituent in the same position gave only 2-aminopyridines (10) and no 1, 3-diazepines. However, the thermolysis of 3-, 5-, or 7-substituted 1, 2-diazepines with either an electron-donating or-withdrawing substituent did not give 1, 3-diazepines. Heating of the bicyclic compounds (8) also gave the corresponding 1, 3-diazepines. Based on these results, we concluded that the presence of an electron-donating substituent is essential for this ring-conversion of 1, 2-diazepines into 1, 3-diazepines. These substituent effects and the reaction mechanism are discussed.
    热分解在 4 位或 6 位上具有一个电子奉献取代基的 1,2-二氮杂卓(7a-f 和 11),可生成 1,3-二氮杂卓(9 和 12)和 2-氨基吡啶(10),而在同一位置上具有一个电子抽取取代基的 1,2-二氮杂卓(7g-k)则只生成 2-氨基吡啶(10),而不生成 1,3-二氮杂卓。然而,热分解 3-、5-或 7-取代的 1,2-二氮杂卓,无论其取代基是给电子还是抽电子,都不能得到 1,3-二氮杂卓。加热双环化合物 (8) 也能得到相应的 1,3-二氮杂卓。根据这些结果,我们得出结论:1, 2-二氮杂卓环状转化为 1, 3-二氮杂卓的过程中,必须存在一个电子奉献取代基。本文讨论了这些取代基的作用和反应机理。

    Thermolysis of the 1H-1,2-diazepines having an electron-donating substituent in the 4- or 6-position affords the corresponding 1,3-diazepines, whereas 1,2-diazepines having electron-withdrawing substituents do not show this ring-conversion.
    在4-或6-位具有给电子取代基的1 H -1,2-二氮杂进行热解,得到相应的1,3-二氮杂s,而具有吸电子取代基的1,2-二氮杂do没有显示该环-转换。

    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)。
  • Studies on diazepines. XXIII Reactions of monocyclic 1H-1,3-diazepines. 1 Cycloaddition reaction with 2,5-dimethyl-3,4-diphenylcyclopentadienone.

    The thermal cycloaddition reaction of 1-ethoxycarbonyl-1H-1, 3-diazepines (4a, b) with 2, 5-dimethyl-3, 4-diphenylcyclopentadienone (5) gave three kinds of 1 : 1 cycloadducts, exo [6+4]π (6), syn-endo [4+2]π (7), and anti-endo [4+2]π (8) cycloadducts, the structures of which were elucidated by spectral analyses and the following photochemical study. Irradiation of the [4+2]π cycloadducts 7 and 8 resulted in an intramolecular [2+2]π cycloaddition to afford the cage compounds 12 and 13, respectively, while the [6+4]π cycloadducts (6), upon irradiation, underwent a retro-reaction to give the bicyclic compounds (11), presumably via the parent 1, 3-diazepines (4).
    1-乙氧羰基-1H-1,3-二氮杂卓(4a,b)与2,5-二甲基-3,4-二苯基环戊二烯酮(5)的热环加成反应产生了三种1:1的环加成物,即外[6+4]π(6)、顺-内[4+2]π(7)和反-内[4+2]π(8)环加成物,其结构通过光谱分析和以下光化学研究得以阐明。[4+2]π环加成物7和8的照射导致分子内[2+2]π环加成,分别得到笼状化合物12和13,而[6+4]π环加成物(6)在照射后发生逆反应,通过母体1,3-二氮杂卓(4)得到双环化合物(11)。
