Vibsane-Type Diterpenoids: Structures, Derivatives, Bioactivities, and Synthesis.

Vibsane-type diterpenoids isolated from the genus Viburnum, are rare 6-11 membered ring polysubstituted macrocyclic diterpenoids. Since the first report of vibsane-type diterpenoids from V. odoratissimum in 1980, they have attracted the attention of scientists due to their complex structures, excellent biological activities, and great synthetic challenges. Recently, there are some notable research achievements on the discovery, synthesis, structural modification, and pharmacological mechanism of vibsane-type diterpenoids. Therefore, we will focus on these aspects to review important achievements of vibsane diterpenoids between 1980-2021.
