Abstract: | Synthesis of novel 3‐(ethoxymethylene)‐pyrano3,2‐c]quinolinone and pyrano3,2‐c]quinoline‐3‐carboxaldehyde was accomplished efficiently via a simple method. These two scaffolds were used as precursors to afford new biologically interesting products in good yield and short reaction times. The chemical reactivity of ethoxy methylene 2 and carboxaldehyde 3 toward different nucleophilic reagents was studied. Structures of the new synthesized compounds were elucidated by their analytical and spectral data. |
