Biomimetic synthesis of natural products via reactions of ortho-quinone methides
… This thesis will describe the use ortho-quinone methides and cascade reactions towards the biomimetic synthesis of the penilactones A and B, the peniphenones A-D, virgatolide B and epicolactone. The total synthesis of ent-penilactone A and penilactone B has been achieved via biomimetic …
