A new chemical sequence for preparing indoles is disclosed whose key reactions are reaction of a o-nitrotoluene with tris(dimethylamino)methane to give a .beta.-dimethylamino-o-nitrostyrene which is converted into a semicarbazone and cyclized.
披露了一种用于制备吲哚的新化学序列,其关键反应是对邻硝基甲苯与三(二甲基氨基)甲烷进行反应,得到β-二甲氨基-邻硝基苯乙烯,然后将其转化为半脲酮并进行环化。
