Abstract

Dibenzoxepines have gained privileged status in medicinal chemistry and drug discovery due to their appearance in various natural products and life-saving drug molecules. Dibenzoxepine-based molecules, such as artocarpols, asenapine, and pacharin, possess a wide range of biological activities including anti-inflammatory, antidepressant, antihypertensive, antiestrogenic, and insecticidal activities. Therefore, designing and developing new methodologies to access the dibenzoxepine­ core has become a paramount research topic for organic/ medicinal chemists. Herein, we reviewed various synthetic methods to access dibenzoxepine derivatives. The total syntheses of dibenzoxepine-based natural products and biologically/medicinally important molecules have also been reviewed.
