derivatives and a dehalogenation into 11,12-dihydropyrido[3,4-c][1,9]phenanthroline. The fully aromatized derivative pyrido[3,4-c][1,9]phenanthroline was obtained in an ultimate dehydrogenation procedure. The condensation of paraformaldehyde with two equivalents of 4-methylpyridine-3-carbonitrile under basic conditions afforded 6-amino-11,12-dihydropyrido[3,4-c][1,9]phenanthroline, which was converted
摘要 在碱性条件下将多聚甲醛与两当量的4-甲基吡啶-3-腈缩合,得到6-氨基-11,12-二氢吡啶并[3,4- c ] [1,9]菲咯啉,其通过相应的6-氧代和6-氯衍生物,并脱卤为11,12-二氢吡啶并[3,4- c ] [1,9]菲咯啉。在最终的脱氢步骤中获得了完全芳香化的衍生物吡啶并[3,4- c ] [1,9]菲咯啉。 在碱性条件下将多聚甲醛与两当量的4-甲基吡啶-3-腈缩合,得到6-氨基-11,12-二氢吡啶并[3,4- c ] [1,9]菲咯啉,其通过相应的6-氧代和6-氯衍生物,并脱卤为11,12-二氢吡啶并[3,4- c ] [1,9]菲咯啉。在最终的脱氢步骤中获得了完全芳香化的衍生物吡啶并[3,4- c ] [1,9]菲咯啉。
