Nature synthesizes many diverse polycyclic, stereodense natural products. Such molecules are also often the targets of laboratory syntheses. We are exploring the mechanisms of key cascade reactions used both in biosyntheses and biomimetic laboratory syntheses of many complex natural products - representative examples are shown above and representative papers are listed below.
