Abstract
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 aromatic compounds 7 by heating with nitrobenzene. Only a few quino[3,2-c][1,8]naphthyridines were previously described.File in questo prodotto:
