for synthesizing aza-heterocyclic compounds using N-tosylhydrazones as key reagents. Our primary objective was to obtain six or seven-membered ring heterocycles; however, we unexpectedly observed the formation of bi-indole compounds in high yields. Furthermore, our synthetic pathway enables modifications at the C3 or C2 position of the indole, leading to the formation of the respective 3′-phenyl-2′-biindole
在这项研究中,我们提出了一种使用N-甲苯磺酰腙作为关键试剂合成氮杂杂环化合物的方法。我们的主要目标是获得六元或七元环杂环;然而,我们出乎意料地观察到以高产率形成双吲哚化合物。此外,我们的合成途径能够在吲哚的 C3 或 C2 位点进行修饰,从而形成相应的 3'-苯基-2'-联吲哚或咔唑衍生物。
