herein a new method for the synthesis of 4-aryl-3,4-dihydro-2H-benzo[g]chromene-2,5,10-triones 4 that proceeds in good yields (74–86%) and mild reaction conditions between readily available 2-amino-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carbonitriles 1, and formic acid (88%), at reflux for 6 h. In addition, we have also studied the antioxidant activities using DPPH and total TAC methods. GRAPHICAL
摘要 我们在此报告了一种合成 4-芳基-3,4-二氢-2H-苯并[g]色烯-2,5,10-三酮 4 的新方法,该方法以良好的收率 (74–86%) 和温和的容易获得的 2-amino-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carbonitriles 1 和甲酸 (88%) 之间的反应条件,回流 6 H。此外,我们还使用 DPPH 和总 TAC 方法研究了抗氧化活性。图形概要
