An intramolecular approach towards the regioselective construction of 2,3-diarylated indoles is reported. The reaction follows an intramolecular electrophilic N-H and C-H bond functionalization between the aniline and acetylene. This methodology employs the concept of a traceless tether to provide access to the free 2,3-diarylated indole products comprising a total of 18 examples. Hypervalent iodine reagents were identified as suitable promoters and four different protocols are provided, including stoichiometric and catalytic transformations.
报道了一种用于区域选择性构建2,3-二芳基吲哚的分子内方法。该反应遵循苯胺和乙炔之间的分子内亲电N-H和C-H键官能化。这种方法采用无痕连接的概念,以获得总共18个实例的游离2,3-二芳基吲哚产物。高价碘试剂被确定为合适的促进剂,并提供了四种不同的方案,包括化学计量和催化转化。
