Overview

This method demonstrates efficient synthesis of indole derivatives in a modular approach, suggesting applicability for broader organic reactions.

Key Points

  • The aim was to develop a concise strategy for synthesizing indole-fused azepino and azocino derivatives.
  • Utilized isatin derivatives as starting materials.
  • Employed allyl-metal addition and Grignard-mediated reactions.
  • Implemented 1,2-allyl migration under acid-catalyzed conditions.
  • Successfully synthesized indole-fused azepino[1,2-a]indoles and azocino[1,2-a]indoles.
  • Established efficiency of the modular synthesis approach.
