7-Hydroxy-3-phenoxy-8-formylchromones, analogs of natural flavonoids

7-Hydroxy-3-phenoxy-8-formylchromones were synthesized using the Duff reaction and were reacted with 2,4-dinitrophenylhydrazine to produce hydrazones and with an excess of hydrazine hydrate to produce the pyrazole recyclization products. Derivatives of α-pyrono[2,3-f]chromones were synthesized using...

Zusammenfassung:7-Hydroxy-3-phenoxy-8-formylchromones were synthesized using the Duff reaction and were reacted with 2,4-dinitrophenylhydrazine to produce hydrazones and with an excess of hydrazine hydrate to produce the pyrazole recyclization products. Derivatives of α-pyrono[2,3-f]chromones were synthesized using the Knoevenagel condensation with 2-azahetarylacetonitriles and the Perkin reaction.
