Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies

European Journal of Organic Chemistry, EarlyView.
A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.
