Abstract
The reaction of aliphatic or cyclic enaminoketones with pyridine or pyrimidine derivatives leads to pyrido[2.3-d]-pyrimidines (3 a-h), benzo[6′.7′]cyclohepta[1′.2′: 4.5]pyrido-[ [2.3-d]pyrimidines (6 a-c), benzo[f]pyrimido[4.5-c]isoquinolines (6 d-e), benzo[3.4]cyclohepta[1.2-c][1.6]naphthyridines (7 a) and naphtho[2.1-c][1.6]naphthyridines (7 b).
