4-endo]nonene (VII; 4%), accompanied with the primary amines, endo-form (XIa; 20%) and exo-form (Xa; 5%), and a secondary amine, benzo-3-azabicyclo-[3.2.2]nonene (IX; 3%). For structure elucidation of the aziridines, IIA, VI and VII, their syntheses by independent method and cleavage reactions with acids were performed. This new method for aziridine formation was examined on some related ketoximes of
发现在回流的THF中用LAH还原二苯并双环[2.2.2]辛二烯-7-肟(I)可以得到氮丙啶,二苯并-3-氮杂三环[3.2.2.0 2,4 ]壬二烯(IIa),产率为34%,以及7-氨基-二苯并双环[2.2.2]辛二烯(III; 3%)和蒽(IV; 50%)。苯并双环[2.2.2]辛烯酮肟(Ⅴ)的还原也得到了相应的氮丙啶,苯并-3-氮杂三环[3.2.2.0 2,4-外基]-壬烯(Ⅵ; 46%)和苯并-3-氮杂三环[ 3.2.2.0 2,4-内]壬烯(VII; 4%),与伯胺,内型(XIa; 20%)和exo-形式(Xa; 5%)和仲胺,苯并-3-氮杂双环-[3.2.2]壬烯(IX; 3%)。为了阐明氮丙啶,IIA,VI和VII的结构,可通过独立方法合成它们并进行酸裂解反应。在桥接环系统的一些相关酮肟上研究了形成氮丙啶的新方法。
