A general method for the synthesis of 2,3-disubstituted indoles is described. The key feature of this method is the amination of aromatic C−H bonds via FeCl2-catalyzed ring opening of 2H-azirines. The method tolerates a variety of functional groups such as Br, F, NO2, OMe, CF3, OTBS, alkenes, and OPiv. The method can also be extended to synthesize azaindoles.
描述了合成 2,3-二取代吲哚的一般方法。该方法的主要特征是通过 FeCl 2催化的 2 H -氮杂环开环使芳香族 CH 键胺化。该方法耐受多种官能团,例如 Br、F、NO 2、OMe、CF 3、OTBS、烯烃和 OPiv。该方法还可以扩展到合成氮杂吲哚。
