A simple and effective method on the basis of Fischer reaction in polyphosphoric acid is proposed for the synthesis of previously unknown heterocyclic structures that contain the 5-chloro-1H-pyrrolo[2,3-b]pyridine system. This method can be used for the synthesis of 3-substituted and 2,3-disubstituted 5-chloro-7-azaindoles with alkyl and aryl substituents.
提出了一种在多磷酸中基于费歇尔反应的简单有效的方法,用于合成包含5-氯-1 H-吡咯并[2,3- b ]吡啶体系的未知结构。该方法可用于合成具有烷基和芳基取代基的3-取代的和2,3-二取代的5-氯-7-氮杂吲哚。
