Tropane and Granatane Alkaloid Biosynthesis: A Systematic Analysis

Molecules, 2016
The tropane and granatane alkaloids belong to the larger pyrroline and piperidine classes of plant alkaloids, respectively. Their core structures share common moieties and their scattered distribution among angiosperms suggest that their biosynthesis may

Total Synthesis of Calyciphylline F. [PDF]

Angew Chem Int Ed Engl
The final challenge in the total synthesis of the caged polycyclic Daphniphyllum alkaloids was the Calyciphylline D‐type alkaloid, featuring a strained 8‐azatricyclo[4.2.1.04,8]nonane ring system. Presented herein is the total synthesis of calyciphylline F, a member of the calyciphylline D‐type alkaloid family, by an intramolecular [4 + 3 ...
