Some 3-substituted-5,6-dihydro[1,8]naphthyrido[3,2-c][1,8]naphthyridines (V) were obtained by the condensation of 7-substituted-2,3-dihydro-1,8-naphthyridin-4-(1H)ones (IV) with 2-aminonicotinaldehyde. All of the 5,6-dihydro derivatives V were transformed into the fully aromatic compounds VI by refluxing with nitrobenzene.
通过7-取代的2,3-二氢-1的缩合反应,获得了一些3-取代的5,6-二氢[1,8]萘吡啶并[3,2- c ] [1,8]萘啶(V),具有2-氨基烟碱醛的8-萘啶-4-(1 H)酮(IV)。通过与硝基苯回流,将所有5,6-二氢衍生物V转化为完全芳族化合物VI。

The preparation of some 3,7-disubstituted-5,6-dihydroquino[3,2-c][1,8]naphthyridines (6) by the condensation of 7-substituted-2,3-dihydro-1,8-naphthyridin-4-(1H)ones (5) with o-aminoacetophenone or o-aminobenzophenone is described. All the 5,6-dihydroderivatives 6 were transformed into the fully aromaticcompounds 7 by heating with nitrobenzene. Only a few quino[3,2-c][1,8]naphthyridines were previously
