ic acid with either 5-amino-7-methoxy-2,2-dimethyl-2H-chromene or 5-amino-2,2-dimethyl-2H-chromene afforded diphenylamines 14 and 15. Trifluoroacetic anhydride mediated cyclization gave the corresponding acridones 16 and 17, which were subsequently N-methylated and reduced to 11-aminoacronycine and 11-amino-6-demethoxyacronycine. These two amino compounds, which gave stable water soluble salts, were
2-氯-3-硝基苯甲酸与5-氨基-7-甲氧基-2,2-二甲基-2H-色烯或5-氨基-2,2-二甲基-2H-色烯的缩合得到二苯胺14和15。三氟乙酸酸酐介导的环化反应得到相应的a啶酮16和17,随后将其进行N-甲基化并还原为11-氨基ac啶胺和11-氨基-6-脱甲氧基ac啶胺。产生稳定的水溶性盐的这两种氨基化合物在抑制L1210细胞增殖方面比丙烯醛或6-去甲氧基丙烯醛强2至3倍。
