  PTC‐Promoted Japp–Klingmann Reaction for the Synthesis of Indole Derivatives

  摘要：

  Indole derivatives have been efficiently synthesized from ethyl 2-phenylhydrazono-5-phthalimido-pentanoate and its derivatives, which were obtained by Japp-Klingmann reaction under phase-transfer catalytic (PTC) conditions. Several different phase-transfer catalysts were investigated and dimethyldioctadecyl ammonium chloride (DMDOA) was found to promote this reaction efficiently. Using DMDOA as the PTC, aryl hydrazones were obtained in yields of 90%. The pure aryl hydrazones were then efficiently cyclized to indole derivatives in yields of more than 80%.
