Synthesis of a New Bichalcone via Suzuki–Miyaura Coupling Reaction

Molbank
Unlike the wide number of natural biflavonoids, natural bichalcones are a rare and even less studied class. Nevertheless, some of them have proved their interest in the fight against cancer through their cytotoxic activity against human tumor cell lines.
