一种异常容易的脱氢溴化反应,涉及2-亚氨基-1-(苯乙基)-,2-亚氨基-1-(苯氧基甲基)-或2-亚氨基-1-(苯硫基甲基)的邻溴原子和= NH质子-吡啶(2a-e)合成了三个新颖的桥头氮三环系统:11,12-二氢吡啶并[2,1- b ] [1,3]苯并二氮杂卓(3a,b),6 H-吡啶并[1 ,2- c ] [1,3,5]苯并二氮杂卓(3c,d)和6 H-吡啶并[1,2- c ] [1,3,5]苯并氮杂二氮卓(3e)。如所预期的,这些环化需要碱,例如碳酸钾,和催化剂,例如,铜青铜。不寻常的是,这些反应在甲醇或正丙醇中,在无水条件下或在大量水存在下回流下发生。讨论了这些化合物的pmr光谱。
