Abstract: A new series of functionalized pyrano[2,3-b]quinolines have been prepared in three steps from first condensation of 3-formyl-2-quinolones with Meldrum’s acid, then the corresponding olefins have been alkylated using methyl magnesium iodide, and finally the target compounds have been obtained in good yields after hydrolysis.
