An Effective Method for the Synthesis of New Bis(indole)methane Analogs Using Rosmarinic Acid‐Supported Magnetic Nanoparticles (Nano‐Fe3O4@RA)

Abstract This research presents an effective method for synthesizing new derivatives of bis(indole)methane using rosmarinic acid supported magnetic nanoparticles (nano‐Fe 3 O 4 @RA) as a catalyst. The reaction offers numerous advantages, such as high yield, catalyst reusability, short reaction time, product purification without column chromatography, and a simple procedure. These factors make it an attractive and efficient option in the field of bis(indole)methane construction.
