Ce travail développe différentes stratégies pour la synthèse énantiosélective de sesquiterpènes naturels à partir de chirons obtenus par biocatalyse. La première partie est consacrée aux premières synthèses énantiosélectives de la kopéoline, et de la kopéolone. La synthèse de la structure décrite de la kopéoline est réalisée, les composés ont été entièrement caractérisés. Les résultats montrent que les structures reportées n'ont pas été correctement assignées, et suggèrent une mauvaise attribution des stéréocentres au cours de l'isolement des produits naturels. Ainsi, deux nouvelles structures sont proposées. Les synthèses totales de ces deux dernières structures ont également été réalisées et ont permis de confirmer la révision structurell...
