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.
使用Duff反应合成了7-羟基-3-苯氧基-8-甲醛色酮,并将其与2,4-二硝基苯肼反应生成脒,与过量的水合肼反应生成吡唑环化产物。通过与2-氮杂环丙叉乙腈的Knoevenagel缩合反应和Perkin反应合成了α-吡咯啉[2,3-f]色酮的衍生物。
