An efficient method for constructing 2-acyl-3-aminoindoles frommethyl ketones and 2-aminobenzonitriles is described, in which NaHS·nH2O is used as a novel umpolung reagent for the first time in organic synthesis. Mechanistic studies revealed that the key step involved an Eschenmoser sulfide contraction reaction.
描述了一种由甲基酮和2-氨基苯甲腈构建2-酰基-3-氨基吲哚的有效方法,其中NaHS· n H 2 O首次在有机合成中用作新型的酚试剂。机理研究表明,关键步骤涉及Eschenmoser硫化物的收缩反应。
