Investigation of the formation of phenanthrene and dihydrophenanthrene derivative natural compounds by metathesis method

Phenanthrenes and dihydrophenanthrene derivatives are a rare class of aromatic metabolites found in various plants and marine plants such as Red Algae. Numerous substituted phenanthrenes have been obtained from botanical sources. Additionally, their biological activities have garnered significant interest in pharmaceutical and other areas of chemistry. The synthesise of phenanthrenes and dihydrophenanthrene derivatives and the challenges encountered in the synthetic steps encourage organic chemists to develop new synthesise methods in this field. Generally, these synthesise methods involve multiple steps, focusing on the cyclization and coupling of small molecules. The aim of this study is to investigate the applicability of the metathesis in the synthesise of various natural compounds derived from phenanthrenes and dihydrophenanthrenes. Furthermore, the study aims to explore methods that contribute to overcoming the challenges encountered in multiple reaction steps and propose new approaches and methodologies for synthesise.
