The synthesis of several new 4-amino substituted and 4-unsubstituted 1,10-phenanthroline-3-carboxylic acid derivatives are reported. The 4-amino derivatives (5,6,7) were prepared from 1,4-dihydro-oxo-1,10-phenanthroline-3-carboxylic acid (2) via aromatizadon and 4-chlorination, followed by nucleophilic substitution at C4 by the appropiate alkyl amine. The 4-unsubstituted derivatives (10,11,12) were
报道了几种新的4-氨基取代和4-未取代的1,10-菲咯啉-3-羧酸衍生物的合成。由1,4-二氢-氧-1,10-菲咯啉-3-羧酸(2)经过芳构氮杂和4-氯化反应制得4-氨基衍生物(5,6,7),然后在C4进行亲核取代合适的烷基胺。4-未取代的衍生物(10,11,12)是通过1,4-二氢4-氧代1,1,10-菲咯啉-3-羧酸乙酯的芳构化和4-氯化制备的。通过转化为4-甲苯磺酰肼除去C4上的取代基,然后碱催化消除酰肼基团。这些菲咯啉衍生物被设计为金属离子复合物介导的DNA裂解试剂。在两个系列中,3-羧酸侧链均与β-丙氨酸偶联,以促进其与DNA结合分子的结合。
