Two heterocyclic compounds 12H-chromeno[2,3-b]quinolin-12-one and 6H-chromeno[4,3-b]quinolin-6-one could be synthesized by the reaction of anthranil with 4-hydroxycoumarin under high temperature conditions. The reaction is a thermo-promoted transformation, without the assistance of catalysts or additives, and without the generation of toxic wastes. This one-step reaction is superior to other reported methods for the preparation of such heterocycles.

Key words: high-temperature reaction, anthranil, 4-hydroxycoumarin, synthesis of heterocycles
