Collective synthesis of sesquiterpenoids

Abstract

Sesquiterpene lactones (SLs) are a large family of natural products characterized by structural diversity and complexity. The presence of an α-methylene-γ-lactone ring in the molecules of SLs constitutes their most distinct structural feature and is the main reason for the exhibition of their cytotoxicity, making them prominent structures for anticancers. Despite the constant interest from synthetic chemists, the collective synthesis of SLs remains a challenge, imposed by the difficulty of designing a synthetic pathway that not only provides sufficient quantities for biological screening, but also leads to sufficiently divergent structures of both isomeric forms of SLs (6,12- and 8,12). The aim of the present dissertation was to develop a synthetic pathway leading to sesquiterpene α-methylene-γ-lactones through a suitable common scaffold, which could lead through appropriate chemical transformations to structures that meet the above criteria for the establishment of a collective synthe ...
