Pd/NBE Cocatalyzed Modular Synthesis of 3-Alkenyl-2,3'-bisindoles and Applications in Access to Racemosin B.

Key Points

• The research aims to develop an efficient method for synthesizing 3-alkenyl-2,3'-bisindoles and racemosin B.
• Utilized Pd/NBE cocatalysis for the synthesis process.
• Applied two consecutive one-pot reactions for modular synthesis.
• Successfully synthesized racemosin B and its analogs.
• Demonstrated the utility of the method through the synthesis of bisindoles.
