Abstract
6-Ethyl-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.
