6-Ethy1-4,5-dioxo-5,6-dihydro-4H-pyrano [3,2-c]quinoline-3-carbox-aldehyde (1) was prepared and utilized as a starting material. Carboxaldehyde 1 was subjected to react with a diversity of carbon nucleophiles producing a variety of condensation products as well as heterocyclic rings linked pyrano[3,2-c]quinolines. Also, reaction of carboxaldehyde 1 with p-toluidine, heterocyclic amines and some hydrazine derivatives produced a variety of products. The structures of the new synthesized products were deduced on the basis of their analytical and spectral data.

The synthesis of novel 6-ethyl-4,5-dioxo-5,6-dihydro-4H-pyrano[3,2-c]quinoline-3-carboxaldehyde is described via Vilsmeier-Haack reaction of 3-acetyl-1-ethyl-4-hydroxyquinolin2(1H)-one. The reaction of titled aldehyde with hydroxylaminehydrochloride, under different conditions, revealed its distinctive chemicalbehavior and a variety of products were obtained. This study revealed existence of ring-opening
