Abstract

AbstractA novel method for synthesizing 10H‐indolo[1,2‐a]indole derivatives is reported here. All products are prepared by applying the intramolecular cyclization strategy at room temperature. The reaction was realized through I2/ZnI2 catalyzed intramolecular nucleophilic addition, hydrogen migration, and rearrangement procedures. The electronic effect and steric hindrance have a significant influence on the reactivity. Moreover, the synthetic value of 10H‐indolo[1,2‐a]indole was also exemplified by the selective decarboxylation and aromatization.
