2,7-Diazaphenanthrene was synthesised in moderate yield by the modified Pomeranz-Fritsch reaction by condensing diethoxyethanal with 1,4-benzenebismethanamine, followed by ring closure with 20% oleum, and its spectral characteristics recorded. A similar reaction with diethyl 1,4-benzenebis(3-aminopropanoate) gave either 2,7-diaza-1,8-dimethylphenanthrene or 2,7-diaza-1,8-phenanthrenebis(methylsulphonic
通过修饰的Pomeranz-Fritsch反应,通过将二乙氧基乙醛与1,4-苯二甲胺缩合,然后用20%的发烟硫酸闭环,以中等收率合成了2,7-二氮杂菲。与1,4-苯双(3-氨基丙酸酯)二乙酯进行的类似反应取决于2,4-二氮杂-1,8-二甲基菲或2,7-二氮杂1,8-菲双(甲基磺酸)闭环反应。测试了这些化合物的双甲硫脲对磷脂酶A 2的抑制作用,但发现它们是无活性的。
