The late-stage oxygenation of natural products has been investigated on two studies templates: the polycyclic chalasans, the main topic of this thesis, and onto resinic diterpenes. Concerning the polycyclic chalasans, the envisaged synthetic targets were trichoderone A and trichodermone, two fungal secondary metabolites recently isolated from the endophytic fungus Trichoderma gamsii. In addition to their fascinating structures, these chalasans showed a moderate inhibition against human tumor HeLa cell line, which makes them very attractive for total synthesis. Based on the biosynthesis of PKS-NRPS compounds, the retrosynthetic studies of trichoderone A and trichodermone suggested the possibility of a common biomimetic precursor through bioi...
