室温下在乙醇中存在1,4-二氮杂双环[2.2.2]辛烷(DABCO)的情况下,4-羟基-2 H-苯并[ h ]铬-2-酮,芳族醛和丙二腈的三组分反应可以提供高产率的新型二氢苯并[ h ]吡喃并[3,2– c ]色烯衍生物。通过MTT分析检测的合成化合物在两种人类癌细胞系(MOLT-4,HL-60)中的细胞毒活性。大多数被评估的化合物在微摩尔浓度下对肿瘤细胞系均显示出低抑制活性。
An efficient green synthesis of eight 3-amino-12-oxo-1-aryl-1,12-dihydrobenzo[h] pyrano[3,2-c] chromene-2-carbonitriles may be achieved by a three-component, one-pot reaction between 4-hydroxy-2H-benzo[h] chromen-2-one, malononitrile and various araldehydes in water in the presence of NEt3.
