The first synthesis of a 6,6â²-biindole and 6,6â²-biisatin scaffold is reported with the penultimate step being the formation of the di-heterocyclic ring by Pd(II)-catalysed intramolecular CâH functionalisation and Sandmeyer cyclisation, respectively.
报道了首个6,6′-双
吲哚和6,6′-双
靛红骨架的合成,倒数第二步是通过Pd(II)催化的分子内C–H官能团化和Sandmeyer环化分别形成二杂环环系。
