A new synthesis of 4-halo-1H-indoles has been developed from easily available 2,3-dihalophenol derivatives. The key steps are Smiles rearrangement and a one-pot or stepwise Sonogashira coupling/NaOH-mediated cyclization. Subsequent functionalization allows access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles.
一种新的合成方法已经从易得的2,3-二卤苯酚衍生物中开发出4-卤代-1H-吲哚。关键步骤是Smiles重排和一步法或分步的Sonogashira偶联/ NaOH介导的环化。随后的功能化允许获得多种2,4-或2,3,4位置选择性功能化的吲哚。
