were obtained from 1 and primary alkylamines, whereas the 1,4-diazepine derivative 10 was obtained from 1 and ethylenediamine. Treatment of the bis-base 1,4-di[β -(N-morpholino)propionyl]benzene bis(hydrochloride) (11) with primary arylamines gave the corresponding bis-(sec-arylamines) 12a - b, whereas its reaction with ophenylenediamine afforded the bis[1,5-benzodiazepine] ring system 14. The synthesis
双酮曼尼希碱,N,N-双(β-苯甲酰乙基)甲胺盐酸盐 (1) 与伯芳胺和二胺反应得到酮仲芳胺 3a - e 和 4。哌啶 7a - c 由 1 和伯烷基胺,而 1,4-二氮杂衍生物 10 是由 1 和乙二胺得到的。用伯芳胺处理双碱 1,4-二[β-(N-吗啉代)丙酰基]苯双(盐酸盐)(11)得到相应的双-(仲-芳基胺)12a-b,而其与邻苯二胺得到双[1,5-苯并二氮杂]环系统14。二氮杂环芳环系统15的合成已通过用哌嗪处理11来实现。尝试从 11 和苄胺合成 4-氮杂-[7]-对环烷 (16) 得到 17。 1 或 11 与苯肼反应得到 2-吡唑啉 18 和 19。
