Synthesis of 3-Substituted 5(H)-Oxobenzopyranopyridines and 2,3-Diaryl-4(H)-oxobenzoypyrano-pyrroles

A novel synthesis of coumarins with a pyridine or pyrrole ring fused at 3,4-postion is described.It involves the reaction of 4-aminocoumarin (II) with substituted malonaldehydes and benzoins to afford 3-substituted 5(H)-oxobenzopyranopyridines (IV, VI) and 2,3-diaryl-4(H)-oxobenzoypyranopyrroles (VIII,IX), respectively.Th pyrrolocoumarins (VIII,IX) produce strongly fluorescent green solution in alklai but do not exhibit much fluorescence in neutral solution.
