A convenient and efficient methodology for the synthesis of new C-3 sulfur-substituted indoles under CeCl3·7H2O promotion is reported. Model bis(indol-3-yl)sulfide 4a and bis(indol-3-yl)sulfone 5a proved to display potent antioxidant activity at the low micromolar level, in DPPH, ABTS, and FRAP assays, as well as in the inhibition of the peroxidation of linoleic acid.
报道了一种在CeCl 3 ·7H 2 O促进下合成新型C-3硫取代的吲哚的便捷有效的方法。在DPPH,ABTS和FRAP分析中,双(吲哚-3-基)硫化物4a和双(吲哚-3-基)砜5a被证明在低微摩尔水平下显示出强大的抗氧化活性,并且对亚油酸的过氧化。
