A series of novel triarylmethane derivatives (3a-j) were synthesized by a one-pot, two-component method via Friedel-Crafts alkylation of various electron-rich arenes (1a-j) with a wide variety of aldehydes (2a-j) in presence of the polyethylene glycol (PEG-400) as a green solvent at 50-60 °C in good to excellent yields (76-96 %). Their structures were confirmed by FT-IR, 1H NMR, 13C NMR, mass spectrometry and elemental analysis. All the triarylmethanes were tested and evaluated for their antiviral and antifungal activities. Compounds 3b, 3f, 3g and 3i exhibited highest antiviral activities against tobacco mosaic virus (TMV).
一系列新型三芳基甲烷衍生物(3a-j)通过一锅法、两组分方法,在聚乙二醇(PEG-400)作为绿色溶剂的存在下,以50-60 °C的温度,通过各种富电子芳烃(1a-j)与多种醛(2a-j)的Friedel-Crafts烷基化反应合成,产率良好至优异(76-96 %)。它们的结构通过FT-IR、1H NMR、13C NMR、质谱和元素分析得到确认。所有三芳基甲烷均经过测试并评估了其抗病毒和抗真菌活性。化合物3b、3f、3g和3i对烟草花叶病毒(TMV)显示出最高的抗病毒活性。
