(2-substituted) pyrano[2,3- f ]quinoline-9-carboxylic acids (6 and 7) were prepared from the corresponding 6/7-aminochromen-4-ones via the Gould-Jacobs reaction. The new tricyclic heterocycles 6-8 exhibit moderate antibacterial activity (MIC=16 - 64 μgmL-1) against E. coli and S. aureus Graphical Abstract Heterocycles [f]-Fused onto Quinolones.
