A number of new 2- and/or 3-substituted 1,6-naphthyridines were prepared via Friedländer reactiona with 4-aminonicotinaldehyde and methylene compounds containing α-ketones, Methylene compounds with two reactive α-centers were also used. The facile conversion of the 1,6-naphthyridines into new tricylic ring system is reported.
通过Friedländer反应a,与4-氨基烟碱醛和含有α-酮的亚甲基化合物一起制备了许多新的2-和/或3-取代的1,6-萘啶,还使用了具有两个反应性α-中心的亚甲基化合物。据报道,将1,6-萘啶容易地转化为新的三环系统。
