The reaction of isatoic anhydrides with the anion derived from ethyl o-fluorobenzoylacetate to furnish [1]benzopyrano-[3,2-c]quinolines is described. An analogous reaction with 3-azaisatoic anhydride furnishes 1b, or with tricyclic anhydride 3, system 4 is isolated. Spectral data is also discussed.
