A series of the title compounds has been synthesized starting from methyl 3-hydroxythiophene-2-carboxylate. Its condensation with 2,4-dinitrochlorobenzene provides through compound 4e a way to introduce 7-substituents by means of diazonium salts reactions.
从3-羟基噻吩-2-羧酸甲酯开始合成了一系列标题化合物。其与2,4-二硝基氯苯的缩合通过化合物4e提供了一种通过重氮盐反应引入7-取代基的方法。
