Abstract In the present Ph. D. Thesis, the biomimetic synthesis of the natural products cordiaquinones B, C, J & K, acremines C & G and allomicrophyllone is presented. In addition, a cationic pathway was evaluated for the synthesis of the [6,6,5] carbocylic skeleton of przewalskin B. The “key” reaction for the synthesis of cordiaquinones C, J & K was a selective monocyclization of an epoxy polyene terpenoid by confinement within the cavities of zeolite NaY. For cordiaquinone B, the Lewis acid-catalyzed cyclization of a benzoquinone epoxide was used. Finally, a highly stereoselective and regioselective Diels-Alder reaction between an aryl diene and an alkenyl quinone was used as a key-step for the biomimetic synthesis of acremine G and allomicrophyllone.
