Divergent Syntheses of Euphorbia Diterpenoids: A Relay Rearrangement Strategy Triggered by Pyridinium Ring Contraction.
Euphorbia diterpenoids are a structurally diverse class of natural products renowned for their potent biological activities. Inspired by biosynthetic 1,2-migrations, yet deliberately departing from these pathways, we developed a synthetic strategy that provides collective access to multiple distinct skeletal families t...
