  The Witkop–Winterfeldt oxidation converts tetrahydropyridoindoles into pyrroloquinolones and cinnolines by an unprecedented scaffold rearrangement

  摘要：

  The Fischer indole reaction between phenylhydrazines and tosyl-4-piperidone furnishes tetrahydropyrido[4,3-b]indoles. In a Witkop-Winterfeldt-oxidation using ozone such indole derivatives are converted into medium-sized dicarbonyl ring systems, which cyclize to pyrroloquinolones. A detailed study of the reaction intermediates and the characterization of a cinnoline betaine side product formed by an unprecedented ring closure mechanism are reported. (C) 2010 Elsevier Ltd.

  One linker, broad application: A simple sulfonamide linker for primary and secondary amines was used for the construction of small libraries of privileged indole and quinolone structures on a solid phase. After the synthesis, the products can be liberated ion a traceless manner under electron transfer conditions or according to a “safety catch” principle.

  一个接头，广泛应用：用于伯胺和仲胺的简单磺酰胺接头用于在固相上构建具有特权吲哚和喹诺酮结构的小型文库。合成后，可以在电子转移条件下或根据“安全捕获”原理以无痕迹的方式释放产物。
